1. Make sure the machine is on (plugged into the AC outlet) and
that it is connected directly to the computer using the IEEE-
1284 bi-directional parallel cable. The cable must not go
through another peripheral device (such as a Zip Drive,
External CD-ROM Drive, or Switch box).
2. Make sure the machine is not displaying an error message on
the LCD Display.
3. Make sure no other device drivers, which also communicate
through the parallel port, are running automatically when you
boot up the computer (such as, drivers for Zip Drivers, External
CD-ROM Drive, etc.)
Suggested areas to check: (Load=, Run=command lines in the
winanl file or the Startup Group).
4. Check with you computer manufacturer to confirm that the
computer's parallel port settings in the BIOS are set to support
a bi-directional machine, i.e., Parallel Port Mode-ECP
