9-2 Firmware environment commands
The printer maintains a number of printing parameters in its memory. These parameters may be changed per-
manently with the FRPO (Firmware RePrOgram) commands.
This section provides information on how to use the FRPO command and its parameters using examples.
Using FRPO commands for reprogramming the firmware
The current settings of the FRPO parameters are listed as the optional values on the service status page.
Note: Before changing any FRPO parameters, print out a service status page, so you will know the parameter-
values before the changes are made. To return FRPO parameters to their factory default values, send the-
FRPO INIT (FRPO-INITialize) command. (!R! FRPO INIT; EXIT;)
The FRPO command is sent to the printer in the following sequence:
!R! FRPO parameter, value; EXIT;
Example: Changing emulation mode to PC-PR201/65A
!R! FRPO P1, 6; EXIT;
