I have installed an HP Officejet 6500 Wireless All-in-One Printer - E709n that is working well with a Macbook with 10.6 and PCs with XP and Windows 7. It's a little more expensive but scanning also works over the network to both Mac and PC.
At launch, twelve printers were AirPrint compatible, all of them from the HP Photosmart Plus e-All-in-One series. As of July 2014, that number had grown to about 1,100 compatible printer models from two dozen different manufacturers. The current list can be found on Apple's support site.
