You do not need a printer driver to send a prn file to a printer.
The printer driver on your laptop will format the document in a language
that your printer understands. The DOS copy command will send the data and
formatting commands from the file to the printer. The only requirement is
the printer driver on the laptop must be compatible with the printer on the
desktop. FYI the name "prn" is reserved for the printer, which is why you
can't name a file prn.

Remember to copy with the /B switch for a BINARY copy.
