9 - 2 Firmware environment commands
The printer maintains a number of printing parameters in its memory. These parameters may be changed permanently
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.
The FRPO command is sent to the printer in the following sequence:
!R! FRPO parameter, value; EXIT;
Example: Changing emulation mode to
PCL6
!R! FRPO P1, 6; EXIT;
FRPO parameters
Before changing any FRPO parameters, print out a service status page, so you will know the parametervalues
before the changes are made.
FRPO INIT command can reset all the FRPO parameters to the default settings of the printer.
(!R! FRPO INIT; EXIT;)
