Graphics Control Functions
The set of control codes that are interpreted while in graphics 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 graphics data sequence. This is potentially
useful, for instance, in the cases of the absolute and relative position commands. A valid escape
sequence that is not applicable to graphics mode, such as bold printing mode, will be
implemented for text on exiting graphics. If the printer receives a nonvalid escape sequence while
in graphics mode, then it drops out of graphics mode.
