摘要： 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.

摘要： 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.

摘要翻译： 被校准以适合具有第一尺寸的源打印介质的图被缩放以适合具有第二尺寸的目的地打印介质。 打印机驱动程序确定要缩放绘图的总缩放因子，以适应目的地打印介质。 打印机驱动程序还会确定一个整数缩放因子，打印机将在打印图纸之前使用它来缩放图形。 打印机驱动程序另外确定要作为打印机的分辨率报告给操作系统的虚拟（或“假”）分辨率。 虚拟分辨率等于打印机使用的真实分辨率乘以实际比例因子。 实际比例因子等于总比例因子除以整数缩放因子。 打印机驱动程序向操作系统报告虚拟分辨率。 当打印机驱动程序从操作系统接收到打印输出时，打印机驱动程序在打印输出打印之前将打印输出缩放整数缩放因子。
