This command group is partly supported. With these commands it is possible to set the default input tray, etc.
The INITIALIZE command is used for environment variables that are not stored in non-volatile storage. The variables available in non-volatile storage will not be changed. Use the DEFAULT command to change the variables in non-volatile storage.
When DEFAULT values must be changed, the available environment variables are changed in non-volatile storage.
For example, change the default plexity:
@PJL DEFAULT DUPLEX=ON
For example, change the default font:
@PJL DEFAULT LPARM:PCL FONTNUMBER=45
This becomes effective from the next job. For the change to become effective immediately (i.e. during the current job) the SET command should be use also (after @PJL JOB).
NOTE
For some of the options an LPARM:PCL is required.
