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

6-38 Environment Commands EN
PRTPSERRS, must be set using this option. Variables that are not
personality-specific cannot be set using the LPARM : personality
option.
All port-specific variables must be set using the IPARM: port option.
Variables that are not port-specific cannot be set using the IPARM :
port option.
Default values set with this command affect the printer control panel
value and the feature setting stored in non-volatile RAM (in those
printers that have a control panel and NVRAM). However, these
values do not affect the print environment until a PJL reset condition
occurs (see “PJL Reset Conditions” for a list of printer events that
constitute a PJL reset). Consequently, if you want the default values
to take effect immediately, send a RESET command after sending the
DEFAULT command(s).
A separate DEFAULT command must be sent for each environment
variable you specify. The command may be used to set any
environment variable except the read-only variables. See the
“Environment Variables” section of this chapter for a description of
each environment variable.
Example: Modifying User Default Settings
This example sets page protection to LETTER for all personalities,
and selects the PC8 symbol set for all PCL jobs. A RESET command
follows the DEFAULT commands so that the PJL Current
Environment defaults to the new settings.
