What is a Driver?

A driver is a software program that enables your software applications to access your mopier’s features. For example, when you print a document, the application sets up your print job with formatting commands such as page breaks, font selections, paper tray selections, and number of copies. The driver takes these commands, translates them into a printer language (such as Hewlett-Packard’s Printer Control Language (PCL) or PostScript), and then sends the job to the printer or mopier. The driver’s interface allows you to select various mopier features that other software applications don’t support directly, like automatic stapling.

Typically, a driver must be installed on your computer for each printer or mopier you are using. Each operating system needs a different printer driver. For example, a Windows 3.11 user can user the CD-ROM Install Utility to install the Windows PCL and PostScript drivers. The exception is UNIX, in which there is no operating system driver; instead each application must support the printer directly.

Most applications allow you to access the printer driver through the Properties, Print, Print Setup, or Page Setup commands. Print job settings selected through your application typically override equivalent settings made through the printer driver. Printer settings made in the application or printer driver typically override the corresponding setting made on the mopier control panel.

In some environments, the mopier can send status information back to the operating system. This capability is called bidirectional communication, since information is sent to and from the mopier. In a bidirectional environment, the optional printer accessories are detected and enabled in the driver automatically. In non-bidirectionalenvironments, accessories that are installed in your mopier need to be set manually in your driver. For example, to use the duplexing feature in a non-bidirectional environment, you must enable this feature in the driver.

You must install the complete printing system to get bidirectional communication. In bidirectional environments, the driver automatically detects the existence of those accessories. Drivers must be installed for clients. In some environments, drivers are downloaded automatically to clients.
