Printer Driver

Printer drivers know all details of the printer they support; therefore, printer drivers are unique for each model of printer supported by the operating system. The printer driver is responsible for:

• Displaying a dialog that enables the user to inform the system how the physical printer is configured; for example, which paper sizes are installed.

• Displaying a dialog that enables the user to configure an individual print job; for example, which orientation (portrait or landscape) to use.

• Responding to application queries for available printer capabilities such as color, resolution and forms.

• Converting the GPI commands in a print job to the printer-specific language commands that will produce the expected output. The printer-specific commands are passed to the file system.
