A driver is a group of files that enables hardware devices to connect or communicate with the computer’s operating system. Without these files or drivers, the computer won’t be able to relay messages correctly to the hardware devices like for e.g. Printer. HP also has its driver called the HP Universal Print Driver (UPD). It is an intelligent print driver that supports a variety of HP printers like HP LaserJet printers and MFPs. It is a combination of general purpose driver and HP proprietary extensions which simplifies driver deployment and management. This print driver can also automatically detect and determine the unique print capabilities installed on each device. It allows you to easily locate and print to another printer within your network.
