-

- PostScript Printer Description (PPD) files are human readable text files
- that describe the features of a specific PostScript capable printer. A
- PPD file describes printer features in such a way that a Graphical User
- Interface (GUI) can be built to present the user with a list of printer
- features to choose from. Examples of printer features include paper
- size, supported fonts, paper handling, etc. A PPD file also contains
- PostScript and Job Control Language (JCL) commands to be used to invoke
- the selected features.
-
- The Impressario PPD software parses a PPD file and uses the PPD file
- information to:
-
- - Build a list of supported printers (Printer Manager Add function)
-
- - Build a GUI for controlling the printer (glp Options panels)
-
- - Send the correct PostScript and JCL commands to the printer (the
- Impressario PPD printer driver)
-
- For more information on PPD files see the Adobe document: "PostScript
- Printer Description File Format Specification" available from Adobe
- Systems Incorporated. Version 4.2 of the document was used as the basis
- of the Impressario PPD driver.
-
- SGI supplies a number of PPD files in the directory
- /var/spool/lp/PPD_model. PPD files in this directory have been tested
- with the Impressario PPD driver and the printers that these PPD files
- support will be listed in the Printer Manager.
-
- Additional PPD files can be found at printer vendor web sites and FTP
- sites. Many vendors have a large collection in a single directory that
- can be downloaded. One notable exception is HP. HP PPDs are not
- available in a single location -- they are incorporated into HP supplied
- printer drivers. For this reason you may have to contact HP to get a PPD
- file for a particular printer.
-
- To make the PPD available to the Printer Manager it has to be copied to
- the directory that contains tested PPD files (/var/spool/lp/PPD_model).
- See the file /var/spool/lp/PPD_model/README for details. Note that if
- the Printer Manager is running and a new PPD file is added to
- /var/spool/lp/PPD_model then the Printer Manager should be restarted to
- insure the new PPD file is seen.
-
- A large collection of PPDs for multiple vendors are available from
- Adobe's FTP site at ftp.adobe.com. Most of these files are already
- available on the SGI system and can be found in the directory
- /var/spool/lp/PPD_untested. /var/spool/lp/PPD_untested contains PPD
- files that SGI has not tested with the Impressario PPD driver. They may

- or may not work with the Impressario PPD driver. These files are
- supplied in the impr_print.sw.ppd_unsupported subsystem and are provided
- as a convenience for users who would otherwise have to get them from an
- FTP site. Printers supported by the PPD files in the
- /var/spool/lp/PPD_untested directory are not listed by the Printer
- Manager (see the README file in the /var/spool/lp/PPD_untested directory
- for more information).

- Impressario PPD Driver Implementation" in the Impressario developers
