My boss has caught the bug and is about to order an iPad. He's an ideal user for one - computer illiterate, yet loves his gadgets. What I think would be incredibly useful in our office is to be able to use his iPad as a printer. Due to his computer illiteracy, we waste a lot of paper printing documents/images/drawings for him to approve/markup. Is there a simple method for adding a 'printer' to our windows workstations that actually creates a PDF that is instantly synced to his iPad over wifi (or even better, over 3G while he's out of the office)? Markup is not neccesary, but would be nice. We have a linux server, but also a windows machine that hosts the printers, if a server app is required.
