All PPD files of this driver entry are available in the PostScript Printer Application

Under this entry Oce's PPD files for their PostScript level 3 printers are hosted. PostScript printers are supported natively in Linux and Unix environments, so you only need the PPD file for your printer, no driver executables, to get access to all printing functionality. The PPD contains all information about properties and user-settable options which are specific to the printer and makes printing dialogs show these options and allow the user to control all the printer's functionality.

The PPDs only support the printing functionality of the printers. To use extra functionality, like scanning, faxing, ... you will perhaps need additional software.

Note that these printers work, like all other PostScript printers, with generic PostScript PPD files, but then you will not get access to all the printer specific functionality.
