LPARM : personality — This optional parameter is
used to inquire about printer language-specific
environment variables. For example, you can use this
option to request the default PCL pitch setting.
PCL is a valid personality. Other personalities, such as
POSTSCRIPT, can be added as hardware options. Use
the @PJL INFO CONFIG command to request the
personalities installed in a particular printer.
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.
The IPARM : port option must be used when setting
port-specific variables. Valid values for port for the HP
LaserJet 4PJ printer are SERIAL and PARALLEL.
variable — This parameter specifies the environment
variable about which you are inquiring. For example, the
DINQUIRE DENSITY command requests the default
toner density setting. See Appendix A for a list of valid
variables for each printer. If you require a more detailed
description of a particular variable, see the
“Environment Variables” section in Chapter 6.
