FEATURES

1.1

GENERAL

The LAS50 is a compact, dot matrix, serial printer. It was designed for use in
personal computer systems, office workstations, and small-sized business
computer systems.

The printer is available in four models.

LA50-RA - 120 V
LAS0-RB - 220 V
LAS0-RC - 240 V
- LAS0-RD - 100 V
The printer has an input buffer capacity of 2047 characters.
The LASO receives characters and commands through an asynchronous serial
interface. The interface operates at any of several selectable baud rates up to

4800 baud.
The paper feed mechanism is able to move paper both forward and reverse.

The printhead is mounted on a carriage that scans horizontally across the
paper. The printer is capable of bidirectional printing with automatic print direc-

tion determination. The ribbon is in a disposable cartridge.
The printer operates in either of two fundamental modes: text mode or graphic
mode. In text mode, characters define the functions and character symbols usually associated with alphanumeric printers. In graphic mode, characters define a

single column of 6 dots to be printed, not an entire character image as in text
mode.

FEATURES

1.1.1

Text Mode

In text mode, the printer uses a 9-element impact dot matrix printhead to print

characters in an 8-dot character cell at 100 characters per second. Lines of 80,
96, or 132 characters can be selected to print in the 8-inch wide print region. An
enhanced printing mode is available that allows more fully formed characters to
be printed in a 16-dot character cell at 50 characters per second.
1.1.2

Graphic Mode

In graphic mode the LA50 allows the programmer to print graphic images by
sending data that controls the dot printing elements individually.
1.1.3

COMMUNICATION

2.1

DATA INTERFACE

The LA50 data interface is RS-232C and RS-423 compatible. It does not include

an interface cable but does include a 25-position plug mounted on the rear of

the cabinet. The printer contains the following interface signals listed in Table

2-1 for connection to an interface cable.

2.1.1

Interface Signals

The following paragraphs describe these interface signals.

COMMUNICATION

2.1.1.2 Send Data - The printer sends serial encoded characters on this line.

Although the bit rate within a character may be up to 4800 bits per second, the
character transmission rate from printer to host for any two characters does not
exceed 100 characters per second.

The printer, when transmitting to the host, always includes one stop bit with
each character.

2.1.1.3 Terminal Ready - The printer sends signals on the Terminal Ready line
which indicate the readiness of the printer to send and receive data. When this
signal is ON the printer is capable of sending and receiving data. When this signal is OFF the printer is not ready for communication.

The terminal is ready to send and receive data after it completes its power-up
initializations, and remains ready to communicate indefinitely.
2.1.1.4

Request to Send - The printer maintains the Request to Send line in

the ON condition indefinitely.

2.1.1.5

Ready/Busy - This line carries the Busy/Ready signal, depending on

the setting of the Ready/Busy Polarity switch. The printer is unable to receive

characters if this signal is in the ‘Busy’ state and is able to receive characters if
this signal is in the ‘Ready’ state.

2.1.1.6 Protective Ground - This line is connected via removable jumper into
the chassis ground of the printer. The chassis is further connected to external
grounds through the third wire of the power line cord.

2.1.1.7

Signal Ground - This line establishes the common ground reference

potential for all other interface circuits.
2.2

DATA SYNCHRONIZATION

Data synchronization with the printer is attained by an input buffer used in conjunction with either the XON/XOFF protocol or the Ready/Busy protocol,
depending on the position of the protocol switch.

COMMUNICATION

2.2.1

Input Buffer

All characters received, except nulls and deletes, are temporarily stored in an
input buffer before further processing. Nulls and deletes are ignored and do not
occupy space in the input buffer. The input buffer has a 2047 character

capacity.
If the printer falls too far behind the incoming data, the input buffer overflows

and data is lost. If characters are lost due to input buffer overflow, a single substitute control character (octal 032) is placed in the input buffer at the point of
loss. If a character is received with a parity error, the character is replaced in the
input buffer by the substitute control character (octal 032) thus causing the error

character (reverse question mark) to be printed. The 032 control character, thus
indicates loss of characters, or a character received with parity error.

When the printer is capable of printing, characters are fetched from the input
buffer and printed or otherwise processed as required. When the printer is
incapable of printing, the printer scans the input buffer for printer status request

control sequences even if the input buffer is full.
2.2.2

XON/XOFF Protocol

Using the XON/XOFF protocol, the data source becomes synchronized with the
printer as described below.

After successfully powering up and becoming enabled to send, the printer

sends an XON control character and constantly monitors the number of empty

character positions in the input buffer. When the number is less than 128, the
printer sends an XOFF control character, signaling the data source to temporarily stop sending data. Meanwhile, the printer continues to take characters from

the input buffer and print or otherwise process them. When the number of
empty positions in the buffer exceeds 224, the printer sends an XON control

character, thus signaling that transmission may resume.
The printer also sends an XOFF control character when it is not ready due to

error conditions or operator actions. Running out of paper or detecting a printhead position failure causes an XOFF control character to be sent. The operator

actions of opening the cover or placing the printer off-line also cause an XOFF
control character to be sent.

COMMUNICATION

The printer sends an XON control character whenever an XOFF state is present, and all of the following conditions are true.
e The printer is ready.

e All fault conditions are cleared.

¢ There are more than 224 empty positions for characters in the input buffer.
NOTE:

At power up, an XOFF’ state is assumed.

The printer sends an XOFF control character whenever an XON state is present, and any of the following conditions is true.
¢ The printer is not ready.
e A fault condition occurs.

e There are less than 128 empty positions fer characters in the input buffer.
The printer sends an extra XOFF control character if more than 64 characters
have been received since the first XOFF control character has been sent.
2.2.3

Ready/Busy Protocol

The Ready/Busy protocol is functionally the same as the XON/XOFF protocol.
However, instead of sending an XOFF control character, the printer places the

Ready/Busy signal in the Busy state, and instead of sending an XON control

character, the printer places the Ready/Busy signal in the Ready state.
2.3

DATA TRANSMISSION

The LAS0 printer communicates using serial characters. The serial character

format used must be the same character format used by the computer. Serial
characters are transmitted using a start bit, 7 or 8 data bits, an optional parity bit

and 1 or more stop bits (Figure 2-1). The number of bits and the polarity of the
parity (even or old) is switch selectable. Parity errors can be detected for either
polarity.

National Character Set Switches

The national character set switches are designated SW1-1 through SW1-4.
These switches are initially set to the United States position (all four switches
open). The United States positionis correctfor many DIGITAL systems around
the world, since it makes the ASCII, VT1 00 special graphics, and the
multinational character sets available. In an 8-bit environment, no change in
|
switch settings is necessary.

set
For those systems that do mi have multinational capability, the character
.

switches may be set to match the national character set of the system

Table 3-1 shows the character sets associated with GO through G3 for each
country. Table 3-2 shows the associated switch positions for that country. For
example, if Britain is selected, SW1-1 is closed, and SW1-2, SW1-3, and SW1-4
are open. With this switch selection, GO is the British character set, G1 is the
VT100 character set, G2 is the multinational character set and G3 is the ASCII
character set. With four switch settings, there are 16 possible combinations.
Only 11 are shown in Tables 3-1 and 3-2. The remaining combinations of switch
settings are equivalent to the United States position.
3.3.2 Graphics Aspect Ratio Switch SW1-5

Switch SW1-5 changes the horizontal to vertical dot ratio in graphic mode byis
changing the number of horizontal dots per inch. The number of vertical dots
kept constant at 72 dots per inch.

TEXT MODE

CHARACTER PROCESSING

4.1

TEXT MODE CHARACTER PROCESSING

This chapter describes the terminal’s response to characters received while:

the printer is operating in text mode.

The terminal processes characters in accordance with the American National

Standards Institute (ANSI) standards X3.4-1977. The ANSI system of character

processing is based on the category (printable or control) of a character in the
American National Standard Code for Information Interchange (ASCII) chart
(Figure 4-1). The category of a character is determined by the character’s posi-

tion in the ASCII chart. In the eight column chart, columns 0 and 1 contain the

control characters while the rest of the chart contains printable characters
(except for SP and DEL). The printer is capable of printing from 14 different

character sets which are described in Chapter 5. SP and DEL are always the
same control characters regardless of the character set selected.

NOTE:

The space character can be considered either an information separator

control character or a printable character. It can be considered a printable character because it takes up space in the terminal memory and on the paper when

printed.

The following paragraphs describe the terminal response to both printable
characters and control characters while operating in text mode.
4.1.1

Active Column and Active Line

Active column is the column where the next character is to be printed. Active
line is the line where the next character is to be printed. Column and line numbers begin with one, not zero. Printed characters usually increment the active

column. Linefeeds, vertical tabs, and form feeds increment the active line.

TEXT MODE CHARACTER PROCESSING

The active column and active line are collectively known as active position.
Active position is only loosely linked to the physical position of the printer carriage and paper mechanism. In general, the active column is only recorded

when a character is actually printed. Any previous history of active column val-

ues is insignificant.
4.1.2

Horizontal Advance Increment

Horizontal advance increment (HAI) is a unit equal to the width of a column. The
printer allows HAI values of 1/5 inch, 1/6 inch, 1/8.25 inch, 1/10 inch, 1/12 inch,

and 1/16.5 inch. Column numbers begin with one and are measured in units of
HAI. Column numbers do not have fractional components.

4.1.3

Vertical Advance Iincrement

The vertical advance increment (VA) is the unit of distance between lines. The
printer allows VAl values of

1/2 inch,

1/3 inch, 1/4 inch,

1/6 inch, 1/8 inch, and

1/12 inch. Line numbers begin with one and are measured in units of VAI. Line

numbers may have fractionalcomponents if the vertical pitch changes withina
page.

4.2

PRINTABLE CHARACTERS

In text mode, printable ASCII characters are printed as they are received by the
terminal. If the active column is not greater than the right margin, each received

character is printed and the active column is incremented.
NOTE:

The actual characters printed depend on the printable character set

designated. Refer to the printable character sets in Chapter 5 and Appendix A
for more detail.

Each printable or space character increases the active column by one unit of
HAI. Characters in the octal range of 041 - 176 are normally interpreted as

printable characters. If the active position is within the printable region, each
printable character or space character prints and the active column increases

as required. If the previous character was printed at the rightmost position and
a printable or space character is received, one of two actions occurs, depending on the setting of the right margin switch. If the right margin switch is set to
truncate, the character is ignored. If the right margin switch is set to wrap, an

automatic carriage return and line feed occurs before printing the character.
4.3

CONTROL CHARACTERS

A control character is a single character function whose occurrence in a particular context starts, modifies, or stops a control function. Control functions are
characters that provide control of the printing and processing of characters.
Control functions are not printed.

TEXT MODE CHARACTER PROCESSING

Tables 4-1 and 4-2 list the control characters recognized by the terminal and the
mnemonic and the function performed by the control character when operating

in text mode. All other control characters received by the terminal cause no

action.
NOTE:

|
Each control function listed in this chapter is assigned a mnemonic.

The mnemonic is an abbreviation of the control function name.

Horizonta
tabs-

011

A horizontal tab is a

preselected pointon a line to
which the printhead advances
when a horizontal tab (HT)
control character is received.
The printer has fixed
horizontal tab stops every

eight units of HAI. Tab stops
are associated with column
numbers, not physical
positions on the paper. Thus,
changing horizontal pitch also
changes the physical position
of tab stops.

When no tab exists to the
right of the active column,

the right margin switch

setting takes precedence. If

this switch is set to wrap,
the printer executes an

automatic carriage return and
a line feed. If the switch is
set to truncate, the active
column is set to beyond the
rightmost print column. This

causes the printer to ignore
characters until the active
column returns to within the
printable region.

ESCAPE AND CONTROL
SEQUENCES

5.1

GENERAL

The LA50 uses escape sequences standardized by the American National

Standards Institute (ANSI) to control many of its features. For the LAS0 features
that lack an ANSI standard escape sequence, additional escape sequences

have been defined and are within the extensions permitted by the ANSI system.
ANSI has established a flexible and comprehensive system for transmitting format and editing information. The system can be used with printing terminals like

the LA5S0 as well as with video terminals and printers. The system has the fol‘lowing important advantages.
1. Itis well defined and well documented. This greatly decreases the chances

of incompatible implementations and aids in achieving device independence in output.

2. It has ample provisions for future extensions without sacrificing compati-

bility with older programs. The syntax used in ANSI controls allows a large
number of new controls to be added with little difficulty.
3. It is compatible with all the frequently used communication protocols. In

contrast, many other systems use control codes that are reserved for
communication functions. In these other systems, codes used for line
turnaround, disconnect and synchronization get confused with those used
to send parameter values.

ESCAPE AND CONTROL SEQUENCES

4. It has a flexible parameter passing convention that allows single parameters, multiple parameters, and default parameters. For example, in the
graphic rendition escape sequence, the single parameter ESC [ 0 m

causes bold and underline to be disabled; the multiple parameter ESC [ 1 ;

4 m causes bold and underline to be enabled; and ESC [ n (no parameter
included) uses the default parameter of 0 which is understood.

control the following LAS0 features.

Graphic mode

The escape sequences allow expansion of the control functions beyond the
current limit of the 32 control characters. For compatibility, certain control character positions are left blank where the LA50 does not perform the function
associated with that control character.

Control functions that require parameters are always invoked by control
sequences. For example, setting horizontal pitch is invoked by a control

sequence since the pitch can be set to 5, 6, 8.25, 10, 12, or 16.5, characters per
inch.

The escape and control sequences are described in the following paragraphs. A
summary of these sequences is provided in Appendix B.

Examples of the escape sequences use the ASCII character and the octal
equivalent. For example, in the partial line down escape sequence ESC K (033
113), the K is the ASCII character and the 033 113 is the octal code for the ESC
and K, respectively.

ESCAPE AND CONTROL SEQUENCES

5.2.1

Partial Line Paper Motion

The following sequences cause partial line paper motion.
Partial Line Down (PLD)

ESC

033

113

The above sequence moves paper forward (upward) 1/12 inch.
Partial Line Up (PLU)

ESC

033

114

The above sequence moves paper reverse (downward) 1/12 inch.
The PLD and PLU sequences do not modify active line. Unless an equal number

of PLU and PLD sequences are sent to the printer, the page boundary reference
will have changed. Thus, PLD and PLU sequences may be used for remote

adjustment of the form position, such as for modifying the top-of-form position.
5.2.2

Horizontal Pitch Selection

When the horizontal pitch changes, the printer converts the active column to the

new horizontal pitch. The computation may yield a fractional component that is

rounded up to the next integer so that all printing is on the column grid for the
selected pitch. A variable amount of white space is included in the line at the
point of horizontal pitch change.

As an example, consider a horizontal pitch of 10 characters per inch in a line
that is to be converted to a horizontal pitch of 12 characters per inch. The pitch
is to be changed after the third character is printed (Figure 5-1).

The division performed above is integer division wherein any non-zero remainder rounds the quotient up to the next higher integer.

Changing horizontal pitch sets the rightmost position for printing to the specified maximum column and sets the single- or double- width attribute of characters as follows.

Double-width characters are considered to be one column wide, not two columns wide. Therefore, tab stops are every eight double-width columns in
double-width pitches, and double-width characters are printed on a doublewidth grid.

ESC[

033 133 070 167

The above sequence sets horizontal pitch to 8.25 characters/inch (HAl =
1/8.25 inch).

5.2.3

Vertical Pitch Selection

When the vertical pitch changes, no paper motion occurs, and the printer converts the active line to the new vertical pitch. The computation may yield a fractional component which is retained.

For example, assume a vertical pitch of 5 lines per inch is to be changed to a
vertical pitch of 6 lines per inch as shown in Figure 5-2.
Note that the fractional component of vertical pitch occurs at the end of the

page because there is no paper motion during change of vertical pitch. This is
unlike the change of horizontal pitch where the fractional component occurs at
the point where the pitch is changed.

5.2.4

Page Length Selection

At power-up time, the page length is set to 11 inches, corresponding to 66 lines
with the default vertical spacing.

The page length command sets the page length in inches. This is accomplished

by providing a parameter representing the number of lines per page from 0 to
252. To calculate the desired parameter, (Pn) use the following equation.

Parameter (lines/page) = desired page length (inch/page)
X current vertical pitch (lines/inch)

The page length can be set to any length from 1/12 inch per page to 21 inches
per page in VAI units at the current vertical pitch. Or, if the page length is set to
zero, the printer has no paging - all form feed characters are equivalent to line
feed characters.

If the desired page length exceeds 21 inches then the printer sets the page
length to 21 inches.

The following sequence sets the page length.

"ESC [

The above sequence sets active line to top-of-form position and sets page

5.2.5

Character Set Selection

The normal mode of the printer is text mode. In text mode, the printer is capable

of printing the 94 printable characters of the ASCII character set, the 81 additional characters of the multinational character set, the 63 additional characters

of the JIS Katakana character set, the 27 additional characters of the VT100
special graphic character set, and the error character, which is a reverse question mark.

The 266 different characters are grouped into the 14 character sets in Appendix

A. Each character set contains 94 characters. Many of the 266 characters
appear in several character sets.

The printer is considered to be in 7-bit mode if the number of data bits has been

set to 7 (refer to Chapter 3). In 7-bit mode, all characters are printed from the GL
character set.

The printer is considered to be in 8-bit mode if the number of data bits has been

set to 8 (refer to Chapter 3). In 8-bit mode all characters are printed from the GL
character set if the eighth bit is 0 or from the GR set if the eighth bit is 1. The

advantage of 8-bit mode is that two character sets (one in GL and one in GR)
can be resident simaltaneously.

ESCAPE AND CONTROL SEQUENCES

A set of commands cause the GL and GR sets to select one of four intermediate

pointers, GO through G3. These pointers can be set to provide access to any of
the 14 available character sets. Table 5-1 lists the commands and designate
how the pointers select the GL or GR set. For example, the LS2 command

causes the GL set to select the character set assigned to G2 and the LSR1 command causes the GR set to select the character set assigned to G1.
The character set escape sequences assign the character sets to the pointers

as shown in Table 5-2.

Printer Status Report

The printer is capable of sending brief and extended status reports. The reports
may be solicited or unsolicited. Unsolicited reports, if enabled, are sent when
any reportable status condition changes state. Unsolicited status reports are
initially disabled. The following illustrates the specific formats and contents of
the brief and extended printer status reports.

The only reportable hardware failure is printhead position failure.

Communication failure may be parity or framing error or receipt of an erroneous
character. Failures designated as events are reset upon sending an extended
report, and are reportable only when they occur - not when they are reset.

ESCAPE AND CONTROL SEQUENCES

5.2.11

Escape Sequences with 8-bit Equivalents

In 7-bit mode, there are 34 possible control characters as shown in columns 0
~and 1, the SP in column 2 and the DEL in column 7 (refer to Figure 4-1).

Not all of these control charabters are used by the LAS50. The control characters
used are shown in Appendix A.

Two character escape sequences from ESC @ (033 100) to ESC — (033 137)
can be replaced by an equivalent control character from 200g to 237g in 8-bit

mode. These 8-bit control characters are mapped on a 1-to-1 basis with the

two-character escape sequences.

For example, the ESC K (033 113g) sequence for partial line down can be
invoked in 8-bit mode by a control character of 213g. The control character
causes the data to be compressed, since only one character, rather than two, is
required. Another example is the ESC L (033 114) sequence for partial line up
which can be replaced by a control character of 214g in 8-bit mode.
5.2.12

Entering and Exiting Graphic and Text Mode
Graphic mode provides a means for selectively printing individual dot patterns,
rather than predefined characters from the character set table.
The ESC P q (033 120 161) escape sequence is used for entering graphic mode.
If an ESC P is sent, the LA50 looks for a lowercase q. If it receives a digit (60 to
71g) it ignores the digit and looks for the lowercase q. When it receives the
lowercase q, it enters graphic mode.

The following escape sequences cause the printer to enter a null state.

ESC __

033 137
ESC ]

033135

ESC
033136

ESCAPE AND CONTROL SEQUENCES

The above escape sequences are for compatibility with future software which
may assign significance to these sequences. In the null state, the printer
ignores everything until a substitue (SUB), cancel (CAN), or escape (ESC) control character is received, or until an ESC \ (033 134) escape sequence in 7-bit
mode or a 220 (octal) control character in 8-bit mode is recgived. With the

exception of the SUB character, any of these conditions will.cause an exit from
graphics mode to text mode or from the null state to text mode. If the printer
receives a SUB character in graphic mode, it causes one column of no dots
(graphic space) to be printed and the printer does not enter text mode.

\ escape
The preferred exit from graphic mode to text mode is via the ESC
sequence, or the 220 control character.

5.3

GRAPHIC MODE

In graphic mode, the graphic patterns are specified by sending characters in
the range of 077 to 176 octal to the printer. Each of these 64 possible
characters specifies a unique pattern formed by the upper six dots of the
printhead. The bottom three dots are not used.

The pattern printed is determined by subtracting an offset of 077 octal from
the octal value of the character. The result is an octal number with a binary
equivalent. Where there isa 1 in the binary number, a dot is printed. The result
is read from top to bottom with the least significant bit being at the top.
“@” (100 octal) is sent to the printer, only the top
For example, if the character
dot will be printed.
100 octal

-77 octal (offset)
01 octal or

Least significant digit

000 001 binary

o)
O

O

If an attempt is made to print past the rightmost position, the printer auto-

matically executes a graphic new line.

5.3.1

ESCAPE AND CONTROL SEQUENCES

Graphic Control Characters

Graphic control characters are characters in the octal range of 040 - 076.
Characters not assigned are ignored. The others are processed as follows.

Octal

ASCII

Action

Code

Symbol

Performed

041

Repeat introducer

044

‘Graphic carriage return

055

—

Graphic new line

5.3.2

Graphic Carriage Return

The graphic carriage return character “‘$" (octal 044) causes the carriage to
move back to the position where the first graphic character was printed after
entering graphic mode. This feature allows you to overprint lines of graphic data
starting at the same horizontal position.

5.3.3

Graphic New Line

The graphic new line character *‘-"’ (octal 055) causes the carriage to move back

as with graphic carriage return, and moves the paper forward (upward) 1/12

inch. This feature allows printing consecutives lines of graphic data starting at
the same horizontal position.

5.3.4

Repeat Sequence

The following is a repeat sequence.
<repeat introducer> <numeric parameter> <printable character>

The repeat introducer is the graphic control character ‘!’ (octal 041).

The numeric parameter specifies the number of times to print the character that
follows. The numeric parameter is a string of characters in the octal range of

060 - 071 which is evaluated as a decimal number. If a numeric parameter is not
received, or a parameter evaluates as 0, a value of one is assumed. If the

parameter evaluates to a value larger than 65535, a value of 65535 is assumed.
All decimal digits shall be processed as part of the count.

ESCAPE AND CONTROL SEQUENCES

The printable character (a character in the octal range of 077 to 176) is printed
as many times as specified by the numeric parameter-count. A repeat sequence
has the same effect as receiving the printable character that number of times.
All printable characters end the repeat sequence processing and start the
printing.

All other characters received during a repeat sequence are processed as usual
except for the substitute control character, which is treated the same as a
graphic space character.

The following examples illustrate the repeat sequence.

Repeat Sequence
0

041 061 060 077

Function
Repeat ten graphic spaces.
|

Repeat six patterns of top dot only.

041 066 100

Graphic Substitute

5.3.5

The substitute character is interpreted as being in place of a character or characters received in error. In graphic mode, it is considered to be a graphic space.
If a repeat sequence is being processed, the processing is cancelled and the
number of graphic spaces required by the repeat count is printed. The printer
remains in graphic mode.

5.3.6

State After Exiting Graphic Mode

After an exit condition is met, the printer has the following state.

Horizontal position is the same as just before entering graphic mode.
Horizontal pitch is the same as just before entering graphic mode.

Vertical position is modified according to the control characters received
while in graphic mode.

Vertical pitch is the same as just before entering graphic mode.
