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.

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.

 

EIO Troubleshooting

 

The JetDirect Configuration Page shown in Figure 7-10 contains

 

valuable information regarding the current status of the EIO

 

accessories. Before attempting to troubleshoot a network problem or

 

notifying your network consultant of a problem, always print a

 

Configuration Page.
