Comments During Select Format, you may enter the following IGP/PGL paper
movement commands. All the commands must be entered in UPPERCASE.
These commands can only be used with the Select Format command. If
used at any other time, an error condition may result.

Although the Select Format command enables the IGP/PGL to ignore all
host–generated paper movement commands, you can input IGP/PGL paper
movement commands with Select Format on.
SFON/SFOFF cannot be used during Ignore Sequence (page 4–65).
Also, during the downloading of TIFF and PCX logos, the SFON/SFOFF
commands are ignored, and, instead, the printer receives the raw data.
