Note
The permissible variables and range of values for each
variable may not be the same in all HP LaserJet printer
models. See Appendix A for a list of valid variables, or send
the @PJL INFO VARIABLES command to request this
information directly from the printer.
value — This parameter is the returned value of the
requested variable. For example, if you send the @PJL
INQUIRE COPIES command, and the PJL Current
Environment setting is 65, the returned value is 65,
indicating 65 copies. See Appendix A for variable names
for each parameter.
Parameters:
Comments:
If your application has status readback capabilities, you can
request the current setting of any valid environment
variable. Since the INQUIRE command returns only the
value for one feature, you can send multiple INQUIRE
commands to request information about more than one
feature. If you need information about many variables, the
PJL INFO VARIABLES command returns the PJL Current
Environment settings for all environment variables.
