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.
