Epson iPhone support
Epson has announced that its printers are now supported by EuroSmartz's Print & Share app for the iPhone and iPod touch. With the added compatibility, users can wirelessly print information stored on an Apple handheld; the printer itself must be connected to a computer via networking or USB. Some supported document types include photos, PDF files and general business documents.
Compatible printers include Epson's Artisan 800 and 700 models. The Print & Share software is available from the App Store at a cost of $7.

PDF?
What applications on the iPhone supports printing PDF files or "business documents"? If there are some out there, they've done a good job keeping it a secret!
