Printers that can't print everything will still try
to print as much as they can. They may:
• Substitute characters they can print for
characters they can't print
• Not print some things at all
• Substitute colors they can print for the ones
they can't.
Since there is such a variety in what you can do
on your screen, you will have to try printing
some of these things on your printer to see what
will happen.
When to Suspect Something Is Wrong
with Your Printer
Since your printed copies may not match what is
on your screen, you may be wondering how to
tell if something is wrong with the printer. In
most cases, your printer should handle text
correctly. If the letters and numbers on your
screen are printed correctly, your printer is
probably working. If they are incorrect, you
should consult the booklet that came with your
printer to check it out.
