LP Print Service Configuration Files

The scheduler stores configuration information in LP configuration files located in the /etc/lp directory, as described in the following table.

Caution –

The configuration files listed in this table are private interfaces, and are subject to change in future releases. You should not build software that relies on these files being in their current locations or that relies on the data being in the format currently used.

Table 8–2 Contents of the /etc/lp Directory


File	Type	Description
`classes`	Directory	Files identifying classes provided by the `lpadmin -c` command.
`fd`	Directory	Description of existing filters.
`filter.table`	File	Print filter lookup table.
`forms`	Directory	Location to put files for each form. Initially, this directory is empty.
`interfaces`	Directory	Printer interface program files.
`logs`	Link to `/var/lp/logs`	Log files of printing activities.
`model`	Link to `/usr/lib/lp/model`	The standard printer interface program.
`printers`	Directory	Directories for each local printer. Each directory contains configuration information and alert files for an individual printer.
`pwheels`	Directory	Print wheel or cartridge files.

These configuration files serve a similar function to the /etc/printcap file on lpd-based print servers.

Note –

You can check the contents of the configuration files, but you should not edit them directly. Instead, use the lpadmin command to make configuration changes. Your changes will be written to the configuration files in the /etc/lp directory. The lpsched daemon administers and updates the configuration files.

The /etc/lp/printers directory has a subdirectory for each local printer known to the system. The following example shows the /etc/lp/printers subdirectories of printers sparc1 and luna.

$ ls -l /etc/lp/printers
drwxrwxr-x 2 lp lp 512 Jan 23 23:53 luna
drwxrwxr-x 2 lp lp 512 Jan 11 17:50 sparc1

The following table describes the files within each of the printer-specific directories.

File Name	Description
`alert.sh`	Shell to execute in response to alerts
`alert.vars`	Alert variables
`configuration`	Configuration file
`users.deny`	List of users to whom printer access is denied
`comment`	Printer description

The configuration file for the printer luna, /etc/lp/printers/luna/configuration, would typically appear as follows:

Banner: on: Always
Content types: PS
Device: /dev/term/b
Interface: /usr/lib/lp/model/standard
Printer type: PS
Modules: default
