Digital ANSI-Compliant Printing Protocol Level 3 Programming Supplement

This document is a technical programming supplement for the Digital ANSI-Compliant Printing Protocol (DEC PPL3) Level 3. It provides device-specific information for programmers creating applications for Digital's DEClaser printer family (specifically the 1100, 2100/2200, and 3200 models). The manual covers topics such as logical-to-physical image mapping, initial state values, maximum supported parameter values, paper handling (including duplex and tray selection), font management, Sixel graphics considerations, and error reporting/status codes. It includes appendices for comparing command support across different printer models and supplements the reference manual with new commands and command parameter summaries.
