Programming Commands
To prompt the Printer for a command sequence, the Printer must first receive a
special character called an "attention getter", which informs the Printer that it
is about to receive a command and the type of command it will be. Immediate
Commands, System Level Commands, and Font Loading Commands each have
their own attention getter. The attention getter character is followed by a
"command character" that tells the Printer what action to take.

doing and perform that command. Commands of all types must be in the
following sequence:
