The quickest and easiest way to print graphics on your printer is to use a
commercial graphics program. With such programs you usually create
an image on your monitor and then give 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 FX prints graphics, read
on.
The print head
To understand dot graphics you need to know a little about how the FX’s
print head works.
The print head has nine 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.
