printer driver

file which contains information necessary to operate a printer from within a particular application

In computers, a printer driver or a print processor is a piece of software that converts the data to be printed to the form specific to a printer. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model. Printer drivers should not be confused with print spoolers, that queue print jobs and send them to printer one after the other.
