TUAW reports that HP has added more printers to AirPrint-compatible list

With only a handful of HP printers being compatible with Apple's AirPrint -- after the disappointment of AirPrint's functionality being drastically scaled back in the final release of iOS 4.2 -- users have been left with two options if they want to print directly from their iOS 4.2 device.

One, get your hacking gloves on and install the necessary files from the developer build of Mac OS X 10.6.5 (which were pulled from the final public release). use one of the free or paid utilities to enable shared printing from your iPad via your Mac or PC. Or two, get your hands on one of the compatible HP printers.
