In Appendix E, we showed you the many block graphic characters
provided by the printer. You can use these characters to create bar
graphs, pie charts, or just about any kind of graphic image you can
think of. In addition to block graphics, we’d like to introduce you to
bit-image graphics-for the truly imaginative user who will settle for
nothing less than total control of the printer. You’ll see that its
bit-image graphics give you new capabilities in business applications,
computer art, and even allows you to create your own
“alphabet”!
When you program the printer to perform bit-image graphics, you
literally control every pin on its 24-pin print head. As a result, you
can print as many as 1,440 dots horizontally, and up to 1,320 dots
vertically on an 8 112-x-i l-inch page.

• FOUR MODES FOR BIT-IMAGE GRAPHICS
The printer has four distinct bit-image modes, allowing you to print:
• 8-bit graphics, with 1 data byte controlling each column,
• 16-bit graphics, with 2 data bytes controlling each column,
• 24-bit graphics, with 3 data bytes controlling each column, and
@8x3-bit graphics, in which each byte controls 3 columns of
graphics data and each bit controls 3 pins of the print head.
The relationships between your graphics data and the pins on the
print head are shown in Figures F-l, F-2, F-3 and F-4 for the four
bit-image modes.
