1–7 Introduction
Modes of Operation
The IGP/PGL has six modes of operation that use specific command
sequences to control the IGP/PGL.
•
In the Normal mode, the printer waits for a Special Function Control
Code (SFCC) in order to perform IGP/PGL functions.
•
In Quiet mode all IGP/PGL commands are ignored.
•
In the Create Logo and Create Form modes, the printer produces
graphics such as forms, logos, bar codes, and alphanumeric data.
•
The Execute mode is the IGP/PGL printing mode, which controls when
the actual printing of the bar codes and graphics will occur.
•
The Configuration mode allows you to select specific IGP/PGL
operations for running IGP/PGL files on your printer.
Normal Mode
Normal mode commands print data in a line printer format until a Special
Function Control Character (SFCC) is detected.
Commands accessible in the Normal mode are summarized in Table 1–1 and
fully described on the referenced pages. Some Normal mode commands can
also be used in other modes: Compressed Print, Expand, Ignore, Select
Format, and Vertical Line Spacing, which are Normal mode commands, can
also be used in the Execute Form mode; the Multinational Character Set
command can be used in the Normal or Create modes. Carriage Return, Form
Feed, Line Feed, EVFU commands, and Paper Slew commands also operate
in the Normal mode.
NOTE: All IGP/PGL commands must be entered in UPPERCASE, and each
command line must be followed immediately by a line feed (or
carriage return with line feed terminator) or a paper motion
command.
