Editing Printer driver (section)

=== Windows ===
On [[Microsoft Windows]] systems, printer drivers make use of [[Graphics Device Interface|GDI]] ([[Unidrv]] or [[PostScript|PScript]]-based) or [[XML Paper Specification|XPS]] (XPSDrv). Programs then use the same standard [[Application programming interface|APIs]] to draw text and pictures both on screen and on paper. Printers which use GDI natively are commonly referred to as [[Graphics Device Interface#GDI printers|Winprinters]] and are considered incompatible with other operating systems, although there is software (such as PrintFil) which will make these printers work in a DOS prompt within Windows.

[[Win32]] APIs also allow applications to send data directly to the spooler, bypassing the printer driver; however, few applications actually use this option.

The printer driver is usually located on the C:\Windows\System32\DriverStore\FileRepository folder on a Windows machine.
