If your word processing program allows inserted codes, it will
probably do standard printing without such codes. It is only for
special features that you will need to use inserted codes. For example,
if you want to have headings in wide bold printing (called expanded
emphasized), you would probably have to use inserted codes. For the
program we mentioned above you would type Control-V, then the
code for expanded emphasized, Control-V again, and then the text of
the heading. The codes for expanded emphasized are in Chapter 6 and
Appendix B.
Again, if this sounds terribly complicated, don't worry. Use your
LX-80 with the standard features of your word processing program
until you become more familiar with both of them. Then you can
decide whether or not you need or want to learn to use inserted
codes.
Programming Languages
If neither of the methods described above seems appropriate for
your application, you can write a program in BASIC or any other
programming language to send control codes to your printer. In the
chapter on page formatting you will find examples of such programs.
Just remember that with this method your printer control code stays
in effect for the whole document you print. This method is good for
setting margins, for example, but does not work for italicizing a word.
Now you have some background on how printers work and how
software can communicate with them. Turn to the next chapters to
learn about the specific features of your LX-80 printer.
