Ecamm (http://www.ecamm.com) has released Printopia, a Mac app that lets you share your Mac’s printers with any “capable” iPhone, iPod touch or iPad. It will also add a virtual printer, allowing you to save print-outs to your Mac as PDF files.
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. The software 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.
Double-click to install Printopia, and within seconds you’ll see most any connected printers on your iPhone, iPad or iPod touch. You’ll also see Printopia’s “Send To Mac” and “Send To Dropbox on Mac” virtual printers.
Printopia requires Mac OS X 10.5 or higher. It costs US$9.95; a demo is available for download.
