Set Command - HP Color LaserJet 5500 Technical Reference Manual

SET Command

Syntax:
6-42 Environment Commands
The SET command enables you to change the value of PJL
Current Environment variables for the duration of a PJL
job, or until a PJL reset condition defaults the value. Use
this command to create a job-specific environment.
Note
When the SET command changes the PAGEPROTECT or
RESOLUTION status, printer memory is reconfigured
(except for printer memory in the HP LaserJet 4L printer).
This erases all downloaded fonts, PCL macros, and
PostScript dictionaries, however no I/O data is lost.
Memory is not reconfigured unless the PAGEPROTECT or
RESOLUTION status actually changes from its previous
setting. When these settings are changed, performance is
affected since all processed data is printed before memory
reconfiguration occurs. (Refer to "Commands that Affect
Printer Memory" in Appendix A.)
@PJL SET [LPARM : personality | IPARM : port ]
~ variable = value [<CR>]<LF>
LPARM : personality — This optional parameter is
used to set personality-specific environment variables.
For example, you can use this option to set the PCL
symbol set.
PCL is a valid personality; other personalities, such as
PostScript, can be added into the printer as hardware
options (cartridges or ROM SIMMs). Use the INFO
VARIABLES command to request the range of values for
all personalities in a particular printer.
The LPARM : personality option must be used when
setting personality-specific variables.
IPARM : port — This optional parameter is used to set
port-specific variables. The HP LaserJet 4PJ is the only
printer which supports port-specific variables.
