PictBridge is a historical computing industry standard introduced in 2003 from the Camera & Imaging Products Association (CIPA) for direct printing. It allows images to be printed directly from digital cameras to a printer, without having to connect the camera to a computer. Its formal name is "Standard of Camera & Imaging Products Association CIPA DC-001 — 2003 Digital Solutions for Imaging Devices".[1] CIPA DC-001-2003 Rev. 2.0 has been published in 2007.
PictBridge is typically implemented using USB ports and the USB protocol. PictBridge-capable printers typically have a USB type A port which is connected by cable to the USB port of a PictBridge-capable digital camera (typically a Mini-B). The user selects the images on the camera to print.
PictBridge and free open source software
PictBridge arguably does not qualify as an open standard, as the specification can only be obtained from CIPA after agreement not to disclose any information from the specification to others (section 2.2 of the agreement[2]). In practice, this means that PictBridge cannot be implemented as free software or open source software, other than by reverse-engineering the protocol (perhaps aided by the white paper that CIPA provides[3]), if publishing source code of an implementation of the PictBridge standard is considered to count as "disclosing information" from the specification.
A printer may implement functions similar to a PictBridge printer without the non-disclosure agreement merely by treating the camera's memory as a USB mass storage device, although the user interface for image selection would necessarily be on the printer rather than the camera in this case.
