xPrintServer fills the gap between the productivity of iPads and iPhones and the inability to print from those devices to office networked printers. As small as any iPhone, xPrintServer leverages Lantronix' patented technologies, along with open industry standards to enable wireless printing to nearly any printer attached to a network. No software. No apps to buy. No configuration necessary.
