HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

EN Glossary-7
Internal Fonts
Internal fonts are the fonts resident in the printer when shipped.
Landscape
See Orientation.
Logical Page
The PCL logical page (also referred to as the addressable area)
defines the area in which the cursor can be positioned. Although the
printer does not actually have a cursor (like the blinking underline
character used on most computer terminals), the cursor position
refers to the currently active printing position (CAP). In other words,
the location of the “cursor” is the position on the logical page where
the next character is positioned. You can move the cursor to different
points on the logical page using the cursor positioning commands;
however, the cursor cannot be moved outside of the logical page
bounds.
Macro
A macro is a collection of escape sequences, control codes, and data
downloaded to the printer, whose execution can be initiated using a
single command.
Menu
A list of configurable items. In the nomenclature of this document,
an “item” is one particular configurable entity (such as “Copies”); a
“value” is an “item’s” particular configuration (such as “Copies=10”).
Modified Print Environment
The current printer feature settings constitute the modified print
environment. Whenever a feature setting is altered using escape
sequences, the new setting is recorded in the modified print
environment.
