LG06 / LG12 Text and Graphics Printers

This user manual provides comprehensive guidance for the installation, operation, maintenance, and configuration of the Digital LG06 and LG12 Text and Graphics Printers. These models are described as fast, quiet line matrix impact printers capable of handling both text and graphics.

Key sections of the manual include:

• Introduction: Outlines printer features such as selectable command code protocols (emulating Digital LG02, IBM Proprinter III XL, and Epson FX 850/1050 printers), diverse output controls (printing modes, dot densities, character attributes, bar codes, multinational character sets), two resident graphics protocols (DEC sixel and IBM Proprinter bit-image graphics), and programmable vertical formatting. It also details diagnostics and printing speeds.
• Installation: Guides users through preparing the printer for use, including power requirements, site selection, removal of shipping restraints, cable connections for Centronics parallel, Dataproducts parallel, and EIA-232D serial interfaces, and initial printer testing.
• Operation: Explains daily use, such as turning the printer on/off, understanding operating states (on-line/off-line), using the operator control panel for various functions (loading/unloading paper, setting top-of-form, selecting fonts, replacing ribbons), and clearing paper jams.
• Configuration: Provides instructions for customizing printer settings, including generating configuration printouts, modifying and saving default values, loading configurations, and changing printer emulations.
• Routine Service and Diagnostics: Covers periodic cleaning procedures for exterior and interior components, running built-in self-tests, generating hex code printouts for troubleshooting, and identifying fault messages.
• Emulations: Dedicated chapters describe the specific control codes, escape sequences, graphics capabilities, and character sets for Digital, IBM Proprinter, and Epson FX emulations.
• Graphics and Character Sets: Details how to print graphic images using bit-image patterns, adjust densities, and manage a wide range of character sets, including various international and special graphic sets, and how to construct large mathematical symbols.

Appendices offer detailed specifications on physical characteristics, environmental conditions, electrical properties, printing rates, duty cycles, and in-depth information on bar codes and font file IDs. The manual is structured to allow users to quickly locate information for effective printer operation and maintenance.
