Command Codes
This appendix gives a summary of the command codes which constitute the
complete set of commands for the resident HP DeskJet Plus emulation.
Introduction
When the printer is set for a particular emulation, it will interpret ONLY the
set of commands belonging to that emulation.
A printer command consists typically of one or more characters imbedded in
the flow of data transmitted to the printer. To make the printer understand
which characters are to be interpreted as commands and which as printable
characters, there is a simple built-in convention: all "characters" that have,
according to the character table, a decimal value less than 32 are interpreted as
control codes. Some of them result in an action, when they are received, others
do not. The ones causing printer action can be found in the command code
description.
