Graphics Programs; Programming Languages - Epson Apex 80 User Manual

If you're using the program's print facility, recheck the Command
Summary to make sure you're sending the correct commands.
If you're still having difficulty printing, check the troubleshooting
section in your spreadsheet program's manual or Appendix C of this
manual.

Graphics Programs

The Apex80 is capable of producing finely detailed graphic images.
Although Chapter 6 gives specific information on the graphics
commands, the easiest way to take advantage of the Apex80's
capabilities is with one of the many graphics programs available.
When buying graphics software, always make sure it has a suitable
option to allow printouts on an Apex, LX, EX, or FX printer. Any
program with an option for one of these printers should give excellent
results, using different dot densities to produce a realistic scale of grays.
Most graphics programs have a printer selection procedure, in which
case you should check the list on page 2-1 to find the proper selection.

Programming Languages

Most users rely on application programs to send commands to the
printer. An awareness of programming languages, however, can be
helpful in exploring a printer's potential or troubleshooting a printing
problem.
For example, if you want to set up your application program to send
a command for italic printing, you can use a programming language,
such as BASIC or Pascal, to do a quick printout before setting up the
program.
If, on the other hand, you've set up a program to send a certain
command to the printer, but it's not printing correctly, you can send
the same command with a programming language to find whether the
problem lies with your application program, the command, or the
printer.
