Use the DOS copy command to copy the file to the printer, such as
COPY SAMPLE.PRN LPT1
Note that this will only work if the PRN file was originally created for the
same printer as installed on your machine. It's usually simpler to re-print
the file from the original document.

As a PSto Jeff's correct information:
I would use the /b switch with the copy command as in
copy /b sample.prn lpt1
This causes the copy to be in binary mode rather than ANSI/ASCII.
Otherwise, the print job might terminate before completion if the data
stream happens to contain a bit pattern that matches a printer control
command.
Also, if needed or convenient, the command can process a fully-qualified
path as in
copy /b d:\letters\sample.prn lpt1
Note that this method is geared to printers attached to parallel printer
ports rather than USB.
