We all know the pit you get in the bottom of your stomach when the excitement of using your new iPad is extinguished by the sad reality that you can't actually print from it. You could replace all the printers and copy machines in your home and at your work office with AirPrint-enabled printers. Or you could install 3rd-party software. Or you could buy the xPrintServer. The xPrintServer turns your current network printer into an AirPrint-able printer that the iPad and iPhone can then use. You may now continue killing trees.
