Printopia extends iOS 4.2 for iPhone and iPad AirPrint compatibility to any printer associated with your Mac. That's important because, while AirPrint was one of the most highly anticipated features of iOS 4.2 and Apple boasted that AirPrint mades it simple to print your email, photos, web pages, and documents, by itself it's currently only compatible with 11 printers. Enter Printopia:

Whether you have an inkjet printer plugged into your Mac, a laser printer plugged into your router or even a network printer, if your Mac can print to it, Printopia will share it. Is your printer plugged into your AirPort or Time Capsule? No problem. Printopia translates for your printer, allowing it to speak to your iPhone or iPad even if it's not an AirPrint-compatible printer. Printopia even supports many password-protected printers.

Printopia also adds a "Send To Mac" printer to your network. This virtual printing option will save a PDF or JPG file directly to your Mac. Additionally, users can send files directly to their Mac's Dropbox directory for instant synchronization to the cloud.

It's baffling that Apple did not provide this kind of AirPrint support to begin with, but it's great to have a third party option. Printopia costs $9.95 and a free 7 day trial is also available.
