CHAPTER 5 PJL - 17
6. Always use the PJL RESET command after a job is completed if the SET command is used in the PJL
job.
6.1.4. PJL environment variables
This section lists the PJL environment variables. There are two kinds of PJL environment variables, General
PJL environment variables and Printer language -specific variables. For all variables, except the read-only
variables, value settings can be modified using @PJL SET, @PJL RESET, @PJL DEFAULT, and @PJL
INITIALIZE.
By using the @ PJL INQUIRE and @ PJL DINQUIRE, you can request value settings for the printer
features. For the details of these commands, see the next section.
Note:
1. Use PJL commands only when no printer language commands are available for a desired feature.
2. When setting printer features with PJL, use the SET and RESET commands when you want to affect the
current PJL job only.
If you want to affect more than the current job, use the DEFAULT and INITIALIZE commands.
3. Supported variables depend on your printer model.
