ABSTRACT:
A printer driver uses filters that are operating system-independent and printer-independent. Print requests and corresponding print data are received by the printer driver and converted into an internal representation that is both operating system-independent and printer-independent. The data to be printed is then passed through a print pipeline where one or more of a plurality of print filters are applied to the data. As a final stage in the print pipeline, the data is converted to a printer-dependent representation. In one embodiment, one or more of the plurality of filters used in the print pipeline are stored in a dynamic link library (DLL).
