Printing wireless from an iPad - it's now a dream that has come true. Although be careful, there are only a handful of printers that are compatible with Apple's nifty AirPrint.

All of the 12 models are from HP, seven of which are compatible out of the box, those seven are:

• Photosmart e-AiO D110

• Photosmart Wireless e-AiO B110

• Photosmart Plus e-AiO B210

• Photo Smart Premium e-AiO B310

• Photosmart Premium Fax e-AiO C410

• HP ENVY e-Aio D410

• Photosmart eStation C510

The remaining five require a firmware update to jump to AirPrint compatibility:

• LaserJet Pro M1536dnf Multifunction Printer

• LaserJet Pro CM1415fn Color Multifunction

• LaserJet Pro CM1415fnw Color Multifunction Printer

• LaserJet Pro CP1525n Color Printer

• LaserJet Pro CP1525nw Color Printer

But, if you're printing from a Mac, there is always the AirPrint Hacktivator program which will make AirPrint work on pretty much any printer...
