Chapter 1 The IGP/PGL Emulation

Normal Mode

Normal Mode commands print data in a line printer format until a Special Function Control Code (SFCC) is detected.

Commands accessible in the Normal Mode are summarized in Table 1 and fully described on the referenced page. 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 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.

Quiet Mode

In this mode, the host processes all data as ASCII characters without any IGP interpretation — the IGP is disabled and all IGP commands are ignored. The IGP looks only for the (cc)LISTEN command.
