Key Points to
Remember About
Environments
When using PJL to set the printer to a desired state,
remember the following points.
At the beginning of a PJL job, the current feature
settings are the same as the control panel values or those
features set with the DEFAULT command.
When a printer language is entered, the current feature
settings (Modified Print Environment) become the same
as the PJL Current Environment. From this starting
point, the printer language commands modify the feature
settings. Printer language commands override all other
settings.
The PJL Current Environment settings can be changed
using the SET command. These settings take effect until
the next PJL reset condition.
The control panel settings (User Default Environment)
can be changed using the control panel or the DEFAULT
command. In printers without a control panel, the
default settings are modified with only the DEFAULT
command.
The Modified Print Environment settings are changed
using printer language commands. These settings take
effect for the duration of the printer language job. After a
printer language-specific reset, such as <ESC>E for PCL,
the PJL Current Environment feature settings are
loaded into the Modified Print Environment.
If the SET command is used in a PJL job, always use the
PJL RESET command after the job is completed.
