Graphics
The dot graphics mode allows your printer to produce pictures,
graphs, charts, or almost any other graphics. Because many
commercial software programs use graphics, you may be able to
print pictures or graphs like the following one simply by giving
your software a few instructions.

The quickest and easiest way to print graphics is to use a
commercial graphics program. With such programs you usually
create an image on your monitor and then use a command to send
the image to the printer.
If you use commercial software that produces graphics, all you need
to know about dot graphics is how to use the software. If, on the
other hand, you wish to do your own programming or merely wish
to understand how the printer prints graphics, read on.
The print head
To understand dot graphics you need to know a little about how
your printer’s print head works. The print head has 24 pins. As the
print head moves across the page, electrical impulses cause the pins
to fire. Each time a pin fires, it strikes the inked ribbon and presses it
against the paper to produce a small dot. As the head moves across
the paper, the pins fire time after time in different patterns to
produce letters, numbers, or symbols.
