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