HP PCL/PJL reference - Printer Job Language Technical Reference Manual

EN Environment Commands 6-9
“PJL reset conditions” are listed below. Note that PJL reset conditions
differ from printer language resets (such as <ESC>E). Printer
language resets load the PJL Current Environment values into the
Modified Print Environment. PJL reset conditions are more powerful.
They load the User Default values into the PJL Current Environment,
and also into the Modified Print Environment.
In this document, the term PJL reset condition refers to any of the
following events:
•Power-on
• UEL command (when not between a JOB and EOJ command
pair)
• @PJL INITIALIZE command
• @PJL RESET command
• @PJL JOB or EOJ command
• Control panel reset
• Other printer-specific events (see Appendix A for information
about job boundaries)
