Chapter 7
User-Defined Characters
The FX-286 has several hundred different characters stored in its
Read Only Memory (ROM). Although this number includes draft,
Near Letter Quality, international, IBM, italic, and graphics charac-
ters, sometimes you would like to have a few more. For those occa-
sions when you need a special character or even a whole new
typeface, the FX-286 allows you to create your own characters and
print them just as if they were ordinary letters.
This chapter describes how to use the user-defined character func-
tion in the Epson mode. The IBM Proprinter mode also has a limited
user-defined character function. For information on its use see the
ESCape "=" and ESCape “I” commands in Appendix J.
Defining Your Own Characters
The printout below displays a few such characters to give you an
idea of what can be done, but remember that you can create whatever
you need or want.
It may seem that designing a character and telling the FX-286 how
to print it would be extremely complicated, but in this chapter the task
is reduced to a simple three-step process: planning your character,
running one program that tests your work and calculates the required
DATA numbers, and running another program to put the character in
your printer’s Random Access Memory (RAM) for use whenever you
need it.
After you have created your own characters, you can re-program
seldom-used keys to generate the user-defined characters. For exam-
ple, you will be able to type < to print .
