Graphics Pin Combination Patterns
Once decimal numbers for the various pin-combination
patterns have been calculated, you can store these numbers
in DATA statements separating each decimal value with
a comma. A READ (n) statement in a program LOOP
simplifies the process of sending pin patterns for
column of dots to be printed. A RESTORE statement can
be used to repeat a pattern a variable number of times.
These statements are standard BASIC commands.
Graphics software packages are available for the Epson
which automatically generate the graphics, like bar graphs,
that are usually used with personal computers. These
packages eliminate the need for all the programming men-
tioned in the above paragraph and are also supported by
the printer.

Plotter Graphics
Your printer has the capability to operate as a "plotter."
\
Entire manuals have been written explaining how to send
dot-patterns for plotting using BASIC or any other lan-
guage normally used. Consult one of these. Here again,
software packages are available.

User-Defined Characters
In addition to the standard fonts or character sets, the laser
printer, like the FX-80, can be used to create you own spe-
cialletters, numbers and symbols. Standard character sets
are stored in ROM whereas user-defined characters must
be created and stored in RAM. RAM is generally used as
a text buffer but because the laser printer has more mem-
ory than the FX-80, it may usually be used simultaneously
for user-defined characters. However, a special command
must be sent to print user-defined characters and override
