Abstract
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. When print output is received by the printer driver from the operating system, the printer driver scales the print output by the integer scaling factor before the print output is printed.
