General PJL Environment Variables
The following table lists the PJL environment variables that are not 
printer language-specific. When you use these variables, do not use 
the LPARM : personality option. The range of values for each variable 
may differ for the various printer models. Appendix A lists the 
environment variables and indicates which printers support each 
variable. Another method of obtaining a list of valid variables and the 
range of values for each variable is to send the INFO VARIABLES 
command to request this information directly from the printer. See the 
INFO command in Chapter 7 for more information. You can find 
valuable information about environment variables in the control panel 
sections of the user's manual for each printer.
Note Some environment variables can be modified using the DEFAULT 
command but not the SET command, some can be SET but not 
modified using DEFAULT, and some are read only variables. 
Appendix A lists environment variables, including read only variables, 
for all of the PJL printers.
