A PPD file label describes a grouping of PPD files and refers to a user-selected or default directory name within a PPD file repository. When you use the ppdmgr utility to add a PPD file to the system, you can optionally specify a label. Using labels allows for easier organization of PPD files, which makes for easier identification of PPD files when you add or modify a printer by using Solaris Print Manager.
You can also specify a file label when you request an update or a rebuild of the PPD cache file by using the -u or the -r option . If you do not specify a label, the user default label is assigned to the PPD file. If you request an update or a rebuild of the PPD cache file, the default label is all, which specifies all PPD file repositories.
You cannot specify the all label when adding a PPD file to a system by using the ppdmgr utility with the -a option. See PPD File Labels for more information.
