Print Environment
The group of all the printer’s current feature settings, collectively, is
referred to as the print environment. The printer identifies four levels
of changes of this print environment: the factory default environment,
the user default environment, the modified print environment and the
overlay environment.
Printer Commands
See PCL Commands and HP-GL/2.
Printing Menu
Identifies a few printer features which can be selected from the
printer’s Operator Control Panel, [[Menu]] key. Print menu features
select the user default items, which are included in the print
environment (features which can be selected with printer commands).
Raster Graphics
Images composed of groups of dots are raster images. Pictures in
newspapers or on televisions are examples of raster images. PCL
includes commands for printing raster images.
Reset
Resets are used to return the printer to a known environment.
Depending on the type of reset performed, the printer returns to
either the User Default Environment or the Factory Default
Environment.
A Printer Reset restores the User Default Environment and deletes
temporary fonts, macros, user-defined symbol sets and patterns. A
Printer Reset is performed by sending the
?E command or through
the printer’s control panel (see the printer User’s Manual).
