ENWW Troubleshooting the HP Jetdirect Print Server 198

Improving Reception and Performance

Wireless LAN radio signals can penetrate many indoor structures

and can reflect around obstacles. However, wireless communication

range and performance depends on a variety of factors, including

the number of users, the quality and physical placement of the

wireless hardware, and the sources of radio signal interference (for

example, microwave ovens and cordless telephones use similar

frequencies that may interfere with wireless LAN signals). In

general, the HP Jetdirect wireless print server’s data transfer rates

will decrease with increasing distance, obstructions and

interference.

Symptoms

● The signal strength (see the HP Jetdirect configuration page or

embedded Web server) is poor or marginal.

● Print jobs are excessively slow.

Corrective Actions

● Re-orient the printer or HP Jetdirect wireless print server. In

general, having the print server pointed toward the Access Point

or wireless PC will improve reception and performance.
