HP PCL/PJL reference - Printer Job Language Technical Reference Manual

6-36 Environment Commands EN
DEFAULT Command
The DEFAULT command sets the User Default Environment value for
the specified environment variable. This value is stored in non-volatile
RAM (if the printer has NVRAM) and is activated following a PJL reset
condition. The DEFAULT command does not affect the current print
environment, but takes effect when a PJL reset condition occurs. Use
this command to change the default value for any environment
setting.
For printers that support the PASSWORD variable, the DEFAULT
command will not take effect unless used within a secure job (a job
with the correct password in the JOB command).
Note In situations where the printer is shared by several users, such as
networks, restrict the use of the DEFAULT command using PJL
security mechanisms. This recommendation allows a standard print
environment to be used and avoids having default features changed
by different print jobs. Instead, if a printer feature must be changed
from the default for a particular print job, use the SET command. In
this way, jobs can be successfully printed in any order, since they are
not affected by settings from previous jobs.
When the DEFAULT command is used to change the
PAGE-PROTECT, RESOLUTION, RESOURCESAVE,
RESOURCESAVESIZE, IOBUFFER, or IOSIZEstatus, the printer
memory is reconfigured. Reconfiguring printer memory erases all
downloaded fonts, PCL macros, and PostScript dictionaries, however
no I/O data is lost. Refer to “Commands that Affect Printer Memory” in
Appendix A.

IPARM : port] variable = value [<CR>]<LF>
• LPARM : personality — This optional parameter is used to
set personality-specific environment variables. PCL is a valid
personality. Other personalities, such as PostScript, can be
added as hardware options. Use the INFO CONFIG command
to request the range of values for all personalities installed in a
particular printer.
• LPARM : personality — This option must be used when
setting personality-specific variables.
