IF (1) you have a printer on your parallel port AND it is the same type
of printer that was selected when the prn file was created, THEN from a
command prompt type
copy filename lpt1 /b <enter>
unless the command prompt shows you to be in the same directory in which
the prn file is stored, use the complete path, e.g. "c:\Documents and
Settings\Username\My Documents\thisfile.prn".
Put quotes around the path as shown. The word after the file name is
ELL PEE TEE ONE.
