Graphics
Overview
This chapter explains how the printer produces graphic images.
The quickest way to produce graphic images is to use one of the many
graphics software applications available. Any graphics program that is
compatible with the Epson FX, Proprinter XL, or P-Series emulation should
provide excellent results.

You can also use the Intelligent Graphics Processor (IGP) Printronix
emulation or the Code V Printronix emulation. Both allow you to create and
store forms, generate logos, bar codes, expanded characters, and other
graphics.

Bit Image Graphics
When the printer uses the IBM Proprinter XL or Epson FX emulation, it
creates graphics by accepting bit image graphics data.
creates graphics by accepting bit image graphics data.
Bit image graphics are created by vertically printing the bit pattern of a series
of data bytes. For example, the bit pattern of the ASCII character A (hex 41,
decimal 65) is shown in Figure 4. If we rotate this data byte 90 degrees
clockwise, we have a vertical data byte with the most significant bit (MSB) at
the top. If we then print each 1 (true) bit as a dot, the result is a “bit image” plot
of the ASCII character A.

Text and graphics can be mixed on the same line when the printer plots bit
images in the Epson or Proprinter XL emulation.
