The xPrintServer is a small unit (4.5 x 2.37 x 0.87-in) about the size of an iPhone, with two connections, one for power, and an RJ-45 jack for a 100BASE-T connection to your network. It can also connect to nearby Wi-Fi enabled printers. Once connected to your network or in range of wireless printers, it will find any printer that supports either JetDirect/AppSocket, LPD, or IPP protocols.

Once the xPrintServer finds your network printers, you can then take your iPad, iPad2, iPhone (3GS or later) iPod touch (3rd generation or later) running iOS 4.2 or later, and these printers will now appear in the Print selection. Lantronix recommends that you have one xPrinterServer unit for every 10 printers on your subnet.
