Previously, each manufacturer used a proprietary method for printing pictures directly from their digital still cameras, making it difficult for users to mix equipment from different vendors.
The first version of the DPS standard is expected by February.
Adoption of the DPS specifications is expected on digital cameras on mobile handsets in the near future and, ultimately, storage vendors would be able to develop DPS-compliant products.
DPS, originally developed by Canon, HP, Seiko Epson and Sony, is written for USB (universal serial bus) connections with PTP (Picture Transfer Protocol) as data transfer protocol.
The standard has been designed for scalability and simplicity, using the same interface for all cameras. After a USB cable is connected between a camera and a printer, the user chooses an image on the cameras' LCD monitor.
By pressing a button on the camera, a printer responds and prints out the image. Advanced functions contained in higher-end cameras can be operated by an extended user interface.
