Viewer
To view PPML documents special software will be needed. For instance, if someone wants to retrieve a document out of a PPML archive, the document will have to be converted to an image by a PPML RIP (just as a PPML printer would) This "as printed" image is shown on screen by the PPML viewer software.
Several such viewers exist, including ones from EFI, Hewlett-Packard, Xeikon, and Edmond R&D. PODi also provides a viewer which is widely accepted as the reference implementation for testing PPML output. "CheckPPML" (the PODi viewer) is a virtual PPML consumer that provides error-checking and PDF output in addition to viewing. CheckPPML can be freely downloaded.
