5.9 Graphic Mode
The Series 90PLUS Printer conforms to the full definition of IBM all-points-addressable (APA) graphic
commands. The printer will only print graphics that are 2.8 inches wide (2.4 inches with the narrow print zone)
which can make it difficult to use off-the-shelf graphic generation programs.
If the Series 90PLUS Printer is used with programs that convert text to graphics, the printer will be slower than
if the printer is sent ASCII text. The Series 90PLUS Printer is supported by a Windows' print driver that will
allow applications to select fonts that are supported by the printer.
The Series 90PLUS Printer is not designed to print large quantities of graphical data. If the printer is asked to
print an excessive amount of black, it will break down the job into multiple steps. This protects the printer but
slows the performance. The printer should not be requested to print a white on black image.
