LGplus Series PGL Programmer's Manual

This document is a comprehensive programmer's manual for the Digital Equipment Corporation LGplus Series printers, focusing on the Printronix Graphics Language (PGL) emulation, also known as the Intelligent Graphics Processor (IGP). It provides detailed instructions for users to program and operate the IGP/PGL to produce sophisticated graphics, forms, and various bar codes.

Key aspects covered in the manual include:

• Modes of Operation: Explains the five operational modes of the IGP/PGL (Normal, Quiet, Create Form, Create Logo, and Execute Form) and their respective command sequences.
• Installation and Configuration: Details the necessary upgrade kit components and guides users through configuring printer settings and emulation parameters such as carriage return/line feed codes, autowrap, Special Function Control Character (SFCC) selection, lines per inch (LPI), font choices, and power-on states.
• Commands: Offers an extensive reference for commands used to define and position various form elements, including alphanumeric data (fixed, overlay, dynamic, and incremental), boxes, horizontal and vertical lines, corners, and logos. It also describes commands for controlling print density, character expansion and rotation, and page numbering.
• Bar Codes: Dedicated sections outline different bar code types (e.g., Code 39, Code 128, EAN 8/13, Interleaved 2/5, MSI, POSTNET, UPC-A/E), their structures, command formats, user-defined ratios, human-readable data options, and incremental bar code fields.
• Form Examples and Exercises: Provides practical examples for designing and executing forms and logos, including scenarios for dynamic data and auto-increment fields, along with guidance on planning page layouts.
• Multinational Character Sets: Describes supported character sets, character addressing, substitutions, and user-defined character sets.
• Error Codes: Lists and explains various error messages to assist in debugging IGP/PGL programs.
• Vertical Paper Motion: Explains different methods for advancing paper, including line feeds, form feeds, the paper instruction (PI) line, and the Electronic Vertical Format Unit (EVFU).

The manual aims to enable users to effectively create and manage complex print jobs with graphics and variable data using the IGP/PGL emulation.
