, 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". CIPA DC-001-2003 Rev. 2.0 has been published in 2007.
Implementation
PictBridge is typically implemented using
USB
Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers. A broad ...
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.
Licensing
The PictBridge specification is not an
open standard
An open standard is a standard that is openly accessible and usable by anyone. It is also a prerequisite to use open license, non-discrimination and extensibility. Typically, anybody can participate in the development. There is no single definition ...

, other than by reverse-engineering the protocol, 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
The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device ...
