Windows Printer Driver
A Windows printer driver is a specific type of driver defined by Microsoft that the OS
uses to translate drawing commands by a Windows application to a specific printer’s
command set. A standard Windows printer driver is a graphics page mode driver, and is
not a POS (point of sale) driver. (Have you ever had to open a cash drawer that was
connected to your printer at home?)
