Putting Gemini to Work
computer manual, try this exercise to “test the water:’ Enter this
simple program:
LPRINT CHR$(14); “BASIC”
then, hit the return (sometimes called the “enter” key). That one-
line program establishes communication between your computer
and Gemini. Now enter this line of text:
LPRINT CHR$(27); “Q”; “If I can do this,
I can do anything!”
After entering this line, when you hit the return key (the “enter”
key on some systems), you’ll be sending function codes and text
to your printer. Hit the return and see what happens. If your Gemini
prints out your simple program, you know that you’re ready to take
the plunge with the more advanced sample programs that follow.
I+ I can do this, I can do anything!
If, for some reason, Gemini didn’t get the message and respond
with action, you might do well to turn your computer off and just
read over the remainder of this chapter. A wealth of information
about printer capabilities is presented, even if you don’t qualify
as a “programmer?
If this simple test worked out well for you and your computer
system, get ready because in the next example, you’ll dive off the
“championship” board and try a double back flip into the deep end.

Check the position of the printer DIP switches before proceeding
with the next example. For the IBM-PC, DIP switch number 2-1 on
your Gemini should be “on:’ and the other three should be “off?
Note: Check with Appendices A-F for information about setting
the DIP switches for various computer systems, as well as for
modifications that may be required in order to run the following
program.
If you are using sprocket-fed fan fold paper, roll the paper up
until the perforation is even with the ribbon guide.
Note: Because the paper drive is engaged when the power is “on:’
you should only adjust the paper position when Gemini’s power
is “off? Moving the platen (by turning the platen knob) when the
power is “on” may damage the paper-advance mechanism.
