Checking the Printer with the Computer
The paragraphs below describe ways to check the computer’s connection to the printer. If
you have problems after performing these checks, see Chapter 3, Troubleshooting.
Parallel Connection to an MS-DOS Computer
Once you have connected the printer to the computer, you can test the connection by send-
ing a print screen to the printer. (At the MS-DOS prompt, type DIR and press Enter. Then
press Print Screen or Shift+Print Screen.)
If the printer does not respond, try modifying the MS-DOS MODE command. From the
MS-DOS directory, type the following command and press Enter:
MODE LPTn,,P
In this command, n represents the port you are sending data through (typically LPTl or
LPTB) and P specifies unlimited retries for time-out errors. The computer will respond with
the message:
Resident portion of MODE loaded
Infinite retry on parallel printer time-out
