Within each of the printer-specific directories, the following files can describe the printer:
A typical configuration file for the printer pinecone, /etc/lp/printers/ pinecone/configuration, would look like this:
Banner: on: Always Content types: PS Device: /dev/term/b Interface: /usr/lib/lp/model/standard Printer type: PS Modules: default
The LP print service uses the terminfo database to initialize a local printer; to establish a selected page size, character pitch, line pitch, and character set; and to communicate the sequence of codes to a printer. The terminfo database directory is located in /usr/share/lib.
Each printer is identified in the terminfo database with a short name. If necessary, you can add entries to the terminfo database, but it is a tedious and time-consuming process. Describing how to add entries to the terminfo database is beyond the scope of this book.
The /usr/lib/lp directory contains daemons and files used by the LP print service, as described in Table 6-6.
| File | Type | Description |
|---|---|---|
| bin | Directory | Contains files for generating printing alerts, slow filters, and queue management programs. |
| local* | Directory | Contains LP executables for the local system. |
| locale* | Directory | Contains locale information. |
| lpsched | Daemon | Manages scheduling of LP print requests. |
| model | Directory | Contains the standard printer interface program. |
| postscript | Directory | Contains all PostScript filter programs provided by the SunOS 5.0 LP print service. These filters come with descriptor files in the /etc/lp/fd directory that tell the LP print service the characteristics of the filters and where to locate them. |
*New in Solaris 2.6. Note that the lpNet daemon and lpdata executable files are no longer a part of the /usr/lib/lp directory in the Solaris 2.6 printing environment. lpNet daemon and lpdata executable files are no longer a part of the /usr/lib/lp directory in the Solaris 2.6 printing environment.
The commands used to set up and administer the LP print service are in the /usr/sbin directory, as shown in Table 6-7.
| Command | Purpose |
|---|---|
| accept /reject | Accepts print requests into the printer's queue or rejects print requests. |
| lpadmin | Defines printer names, printer types, file content types, print classes, printer devices, and printer comments; removes printers or print classes; specifies fault recovery, interface programs (either custom or standard), printing options, banner/no banner; mounts forms; mounts printwheels or cartridges; defines allow and deny user lists. |
| lpfilter | Adds, changes, deletes, and lists filters. |
| lpforms | Adds, changes, deletes, and lists forms. |
| lpmove | Moves queued print requests from one printer to another |
| lpshut | Halts the LP print service ( the command lpsched, which starts the LP print service, is in the /usr/lib/lp directory) |
| lpsystem | Registers print servers and print clients with the LP print service |
| lpusers | Sets queue priorities for users |
The LP print service maintains two sets of log files: a list of current requests that are in the print queue (/var/spool/lp) and an ongoing history of print requests (/ var/lp/logs/requests).
The scheduler for each system keeps a log of print requests in the directories /var/spool/lp/requests /system and /var/spool/lp/tmp/system. Each print request has two files (one in each directory) that contain information about the request. The information in the /var/spool/lp/requests/system directory can be accessed only by root or lp. The information in the /var/spool/lp/tmp/system directory can be accessed only by root, lp, or the user who submitted the request.
The following example shows the contents of the /var/spool/lp/tmp/pine directory. See Table 6-8 later in the chapter for an explanation of the LP requests log codes.
pine% ls /var/spool/lp/tmp/pine 2Ø-Ø 21-Ø pine% cat 21-Ø C 1 D slw2 F /etc/default/login P 2Ø t simple U winsor s Øx1ØØØ
These files remain in their directories only as long as the print request is in the queue. Once the request is finished, the information in the files is combined and appended to the file /var/lp/logs/requests, which is described in the next section.
Use the information in the /var/spool/lp logs if you need to track the status of a print request that is currently in the queue.
