  • Providing print preview of a print job using printing calls from a print driver
    Patent number: 5963216
    Abstract: A print preview of a print job is performed. An operating system forwards to a printer driver, printing calls for the print job. The printer driver translates the printing calls to display calls for the print job. The printer driver forwards the display calls through the operating system to a display driver. The display driver displays a representation of the print job on a display.

  • Printing driver and printer which utilize adaptive object banding
    Patent number: 5930469
    Abstract: A drawing is prepared for printing. An analysis of print complexity of the drawing is performed. The drawing is partitioned into print bands based on the analysis of print complexity of the drawing. The print bands are then forwarded in sequential order to a printing device.

  • Versatile scaling of drawings
    Patent number: 5745659
    Abstract: A drawing which is calibrated to fit a source print media with a first size is scaled to fit a destination print media with a second size. A printer driver determines a total scaling factor by which the drawing is to be scaled in order to fit the destination print media. The printer driver also determines an integer scaling factor which is to be used by a printer to scale the drawing before printing the drawing. The printer driver additionally determines a virtual (or "fake") resolution to be reported to an operating system as the resolution of the printer. The virtual resolution is equal to a true resolution used by the printer multiplied by a real scale factor. The real scale factor is equal to the total scaling factor divided by the integer scaling factor. The printer driver reports the virtual resolution to the operating system.
