  • Printer compatability matrix listing compatible and non-compatible print drivers and print drivers compatible with adaptation
    Patent number: 8599393
    Abstract: An exemplary method or device determines which print drivers are being used within a printing environment. The method or device identifies a plurality of print queues. Each of the print queues is associated with one of the print drivers. The method or device submits a plurality of test documents to each of the print queues to produce a plurality of page description language (PDL) files. The method or device identifies print drivers that produce different types of PDL files as being non-compatible. If corresponding PDL files produced by different ones of the print drivers in response to the test documents contain all identical header commands (in any order) the method or device identifies the different ones of the print drivers as being compatible. If corresponding PDL files produced by different ones of the print drivers in response to the test documents do not contain all identical header commands, the method or device identifies the different ones of the print drivers as being non-compatible.
