2 Getting Set Up
2-28 Phaser 220i and Phaser 220e Color Printers
Setting up PC ports (DOS)
Parallel port setup
If you are using the printer's parallel port, you should disable timeouts on
your computer's parallel port. Disabling timeouts ensures that large files
will print, even if data transmission is slow.
The DOS MODE command is used to disable timeouts on your computer's
parallel port. Type this command at the DOS prompt (if LPT1 is not
available, use LPT2):
MODE LPT1:,,P > NUL
See your DOS documentation for details on the MODE command.
You may want to add the MODE command to your AUTOEXEC.BAT file, so
that it takes effect every time you turn on your computer.
