The Print
Environment
Introduction
The group of all of the printer’s current feature settings,
collectively, is referred to as the print environment. The printer
maintains four print environments: the Factory Default
Environment, the User Default Environment, the Modified
Print Environment and the Overlay Environment. This chapter
describes the Factory Default Environment, the User Default
Environment, and the Modified Print Environment (the Overlay
Environment is described in Chapter 12, Macros).
Default settings refer to the settings programmed into the printer
at the factory or settings selected using the control panel. The
term “default” simply refers to the settings the printer uses unless
printer commands select other settings.
Each time a job is printed, some of the printer’s feature settings
may be changed from their default values to produce the desired
printed output for that job. After the job prints, the job-specific
feature settings are longer be required, since the next job is likely
to have different output requirements. The next job should clear
all previous job settings by performing a reset. This allows a job
to start with the default settings as a known base set, and vary
only those settings that are needed. Starting with the default
environment at the beginning of each print job eliminates the
need to set every feature each time a job is run.
Note The print environment features presented in this chapter are for a
variety of HP LaserJet printers. Not all of the features are applicable
to every printer. To identify variations and default settings for specific
printers, refer to Chapter 3 of the PCL 5 Comparison Guide.
