The simplest way to print it is to open a DOS command window by navigating
to the Start Run slot and typing
cmd
followed by pressing enter.
then type copy /b <filename> lpt1
This assumes the printer for which the printer file is written is connected
to lpt1.
Typically, these files should not be edited since they contain data intended
to be sent to a printer and any editing/changes might result in unexpected
printer behaviour.
