I'm little rusty and someone said it a lot better than I, so here's his quote:
"PRN files are not viewable. You can print it from DOS mode or DOS window
with a dos simple copy command like one of the follows (filename is the mane
of the file you print):
COPY filename.prn LPT1
COPY filename.prn LPT2 (if printer is connected to the second parallel
connector)
COPY filename.prn COM1 (if printer is connected to the first serial port)
COPY filename.prn COM2 (if printer is connected to the second serial port)
You can send a .prn file just as another file. The other person can print
this file in the same type of printer. If the other person don't have the
same printer you can printed the file using the driver of the printer the
other person have and pass this file to that person.
E.g. If you have the HP 930 printer and the other have an Epson 740 printer.
You print the document using the Epson 740 driver even if you don't have
this printer. You cannot print this file as a .prn file. But the other
person do print it in his/her printer using the copy command."
Try it.
