Interface Troubleshooting
This section provides an overview of the printer’s interface
requirements.
Communications Check
Note Communication problems are normally the customer’s responsibility.
Time spent attempting to resolve these problems may not be covered
by the product’s Hewlett-Packard warranty.
Refer the customer to the network administrator for assistance in
troubleshooting network problems.
If the printer is not connected to an MS-DOS-based host, proceed to
Table 7-34, “Communications Checks,” on page 7-82.
Test Message
After the printer is installed, verify communications between the
printer and the IBM-compatible computer. Enter the following at the
DOS prompt:
C: \ DIR > LPT1 Enter (for printing to the parallel port)
The printer should print a directory listing of the C: \ directory.
