LG PLUS Series VGL® Programmer's Manual

This document is the Programmer's Manual for the LG PLUS Series VGL (Vector Graphics Language) / IGP (Intelligent Graphics Printing) emulation, dated December 1995. It serves as a comprehensive guide for using the IGP Code V Printronix Emulation software on impact printers to create advanced print outputs.

The manual covers:

• Overview: Introduces the IGP Code V as an Intelligent Graphics Printing emulation that produces on-line forms, bar codes, and alphanumeric text. It highlights features like variable bar codes, expanded/compressed/rotated print, logos, reverse/shaded print, automatic increment/decrement, and multinational character sets.
• Installation & Configuration: Details the contents of the IGP Code V upgrade kit and explains how to configure printer operational settings for the emulation via the control panel, including Special Function Control Characters (SFCC), Lines Per Inch (LPI), graphics options, error handling, font sets, and PI control.

• Commands: Provides an extensive list of commands for controlling printer output in both Normal and Graphics Modes. This includes commands for:

  • Text and Alphanumerics: Setting character height, width, type, compressed print, dark print, descending characters, reverse print, shading, and various rotations.
  • Graphics: Drawing boxes, solid and dashed lines, generating logos, and plotting graphics by columns or rows.
  • Form and Label Generation: Dynamic form creation, field length definition, copying and repeating fields, and utilizing the Electronic Vertical Format Unit (EVFU).
  • Control: Direct printer commands, dot/line slew, horizontal/vertical tabs, resetting settings, ignoring data, and handling command sequences with interrupts.

• Bar Codes: Dedicated section detailing command formats, parameters, and examples for various bar code types including Codabar, Code 39, Code 93, Code 128/UCC 128, EAN 8/13, Interleaved 2/5, MSI, POSTNET, UPC-A, UPC-E, and UPCSHIP, emphasizing size, height, ratios, and check digits.

• Exercises and Examples: Provides practical steps for users to practice creating alphanumeric text, boxes, forms, and labels using the IGP Code V commands.
• Multinational Character Sets: Explains how to access and manage 32 international and user-defined character sets, including character addressing, substitutions, and translation tables.
• Error Codes: Lists and describes error messages generated by the IGP Code V to assist in debugging programs.
• Appendices: Includes reference charts for the Standard ASCII Character Set, shading masks, grid samples, and page boundaries to aid in design and programming.

The manual is intended for programmers to effectively utilize the IGP Code V emulation to produce complex and customized print documents.
