3 – 8 Programming
If your computer is equipped with BASIC, you have an alternative to
selecting features. After you load BASIC, run a simple one or two line
program telling the printer to change a feature(s).
Without turning the printer off, load and run your software package.
For example, suppose you wanted to print at 12 characters per inch:
1. Load BASIC
2. Type the command: LPRINT CHR$(27);CHR$(58)
Note: You do not have to know how to program to do this, but be sure to check your
computer documentation to see what statement to use (we use LPRINT) before each
command. Not all versions of BASIC are the same.
3. Press RUN, then RETURN or CR.
4. Without turning the printer off, enter your software package.
What you have just typed causes the computer to send a command to the
printer to go into 12 characters per inch mode. When you load and run
your software, all printing thereafter will be at 12 characters per inch
until you turn the printer off or send a command to change the characters
per inch setting.
There is one exception to this method, however: You cannot use this
method if your computer sends an I-Prime signal before you load a
program. An I-Prime signal is sent by some computers to cancel any
special commands that were previously in effect so that you can start
fresh with each new document.
