This looks like an ordinary fax/scanner/printer, but it's actually much smarter than your Average Joe office equipment. By embedding all the necessary information for a particular sender or setting into a QR code, the CP4500it from Ricoh lets you avoid the hassle of messing around with all those often dysfunctional buttons on the conventional machine. Just scan the QR code as the first page of your document, and it will read your settings (file type, contrast/brightness, size, fax #, etc) and automatically do what the QR code tells it to do.

Just think a step further and one can send you all needed information for your printing job via QR Code right on your cell phone. You put it on your Ricoh copy machine and get the job done precisely as it was intended. And I think we are only at the very beginning of this.

That's also why I firmly believe that a standard like QR Code has so many advantages over a proprietory mobile code solution. Suddenly, if everything starts talking QR Code, the possibilities are endless.
