Solaris Print Manager includes a Use PPD files option that enables you to specify a PPD file when creating a new print queue or modifying an existing print queue. If you do not want to specify a PPD file, you can deselect this option.
PPD files are not required for printers that already contain the RIP feature.
When setting up a printer that uses a PPD file, you are required to specify following information:
Printer make
Printer model
Printer driver
