Canon, Fuji Photo, HP, Olympus Optical, Seiko Epson and Sony have developed a new industry standard that will enable consumers to print photos by directly connecting their digital still cameras to their printers.
Until now, each company had its own proprietary solution for direct printing – without a computer – between their own branded digital still cameras and printers.
The unified specification, tentatively named DPS, will ensure compatibility across digital cameras and printers, regardless of brand.
The specification was originally developed by Canon, HP, Seiko Epson and Sony. Fuji and Olympus later joined the discussions and the specification was finalised collectively.
DPS itself specifies an application layer control protocol and is independent from any physical transport. It was designed to be extensible for implementation on future physical interfaces.
The DPS version 1.0 document, which will be published formally later, is written for USB as the physical transport layer and the Picture Transfer Protocol as the data transfer protocol.
