Support for the Use of PPD Files To Set Up Printers

Support for setting up and administering printers with PPD files has been incorporated into the Oracle Solaris print subsystem. Two interface scripts, standard_foomatic, and netstandard_foomatic, are available. These interface scripts provide the generic interface between the Solaris spooler and the back-end process of the print server.

The following are examples of the types of printers that are supported:

Raster Image Processor Support

The raster image support in the Oracle Solaris OS (RIP) enables you to print to printers that do not have resident PostScript processing capabilities. Theprinting software provides the print server RIP and supporting technologies. The RIP occurs behind the scenes. However, to use the appropriate driver you need to configure each printer by using either Solaris Print Manager or the lpadmin -n command. For step-by-step instructions on using the lpadmin -n command, see How to Add a New Directly Attached Printer by Using LP Print Commands.

Support for PostScript Printer Description Files

The lpadmin and lpstat commands, as well as the Solaris Print Manager printer definition screens, support the use of PPD files.

The following new software packages are associated with this feature:

Where to Find Information About Supported Printers and Available PPD Files

Caution – Caution –

The location where the PPD files and the ppdcache file is stored are private, as is the contents of the ppdcache file. The placement of these files and the contents of the ppdcache are subject to change. Do not build software that relies on these files being in their current location or that relies on the data being in the format that is currently used.

If the file required by your printer is not available, you can add your own PPD file. If you use the lpadmin -n command to create a new print queue, you can store your own PPD files anywhere that you choose. If you are running the Oracle Solaris 10 OS, and you use Solaris Print Manager to create the print queue, the PPD file must have an entry in the ppdcache file.

If you are running a supported Oracle Solaris release, PPD files are located in any of following four repositories on the system:

/usr/share/ppd

Specifies the system repository.

/usr/local/share/ppd

Specifies the admin repository.

/opt/share/ppd

Specifies the vendor repository.

/var/lp/ppd

Specifies the user repository.

Copies of PPD files that are specified by using the lpadmin command with the -n option, or by using the -a option with the ppdmgr command are stored in the user repository under the same PPD file name.

If you use the ppdmgr utility with the -a and the -R options, a copy of the specified PPD file can be stored in the admin repository.

If you create a print queue with Solaris Print Manager, and no entry exists for the PPD file in the ppdcache file, you can use the ppdmgr utility to add the file to the system. The cache of PPD file information that Solaris Print Manager uses is then updated to reflect any changes you make by using either of these two methods.

In later Oracle Solaris releases, PPD files are located in the /usr/lib/lp/model/ppd/system directory or any alternate directory that you specify.

The output of the ls command lists all the PPD files for a particular printer manufacturer.
