Open a DOS command window and type
copy /b <filename with fully-qualified path> lpt1
Then press enter.
e.g.:
copy /b d:\utility\hexdata.dat lpt1
Note: The printer attached to Lpt1 must be capable of responding correctly
to the data exactly as it is in the file since no printer or other device
driver will interpret the data.
