Service Set Identifiers (SSID)
An SSID is a logical name assigned to a wireless LAN. It is typically used to provide LAN access control.
For example, if the SSID for a wireless network is “mycompany”, then each wireless device on this
network must be configured with this SSID.
In infrastructure mode, the Access Point will require wireless devices to be configured with the
appropriate SSID before network access is allowed.
Signal range
The range over which wireless devices can communicate depends on the physical environment and the
orientation of the HP Jetdirect print server.
For 802.11g, the range is typically 50 feet at the highest data rate (54 Mbps). Data rate will decrease to
802.11b levels as range, traffic and interference increase.
For 802.11b, the range is typically 100 feet at the highest data rate (11 Mbps), and 300 feet at the lowest
data rate (1 Mbps).
In general, while radio waves can bounce off obstacles to access print servers, it is best to have clear
line-of-sight access between devices without obstacles through which the signal must pass.
NOTE: Signal range and wireless transmission performance is reduced with increasing distance
between devices, and with obstacles that block or absorb signals.
Network printing terms and concepts
Client-server printing
On a client-server network, client computers send print jobs to a dedicated network server that controls
the use of each installed printer. The HP Jetdirect print server receives print jobs over the network under
the network server’s control, or can automatically monitor print queues and de-spool print jobs from the
network server.
