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. EN Glossary-7
