That sounded cool until I read the press release: "A selection of AirPrint enabled printers including the HP Photosmart, HP LaserJet Pro and HP Officejet will be the first to support printing direct from iOS devices." I take that to mean the printer needs to support this, which means AirPrint replaces the driver, and rather than adapt the driver to the OS, the printer adapts to the driver. Is this the case? It would…
You can enable non-AirPrint printers by sharing them through iTunes 10 (PC) or Mac OS X 10.6.5 (Mac).
Mea culpa.
