Graphics Control Functions

The set of control codes that are interpreted while in graph ics mode are shown in the following

charts. Bytes less than 32 decimal that are not interpreted as control codes are ignored. The

printer processes valid escape sequences within a gra phics data sequence. This is potentially

useful, for instance, in the cases of the absolute and relati ve position commands. A valid escape

sequence that is not applicable to graphics mode, suc h as bold printing mode, will be

implemented for text on exiting graphics. If the printer rece ives a nonvalid escape sequence while

in graphics mode, then it drops out of graphics mode.
