Managing printers and print jobs

Adding a new printer manually

The print service relies on the standard interface script and the terminfo database to initialize each printer and set up a selected page size, character pitch, line pitch, and character set. Thus, it is usually sufficient to have the correct entry in the terminfo database (/usr/lib/terminfo/terminfo.lp) to add a new printer to the print service.

The terminfo database identifies each printer by a short name, identical to the kind of name used to set the TERM shell variable. For example, the name in the terminfo database for the AT&T model 455 printer is ``455''.

To specify the terminfo type for your printer, in the Printer Manager select Advanced from the Settings menu, then select Terminfo Type. By default, the terminfo database includes entries for several popular printers. Select the terminfo type from the list that corresponds to your printer.

If terminfo does not include an entry for your printer, you might still be able to use the printer with the print service. However, you will not be able to use automatic selection of page size, pitch, and character sets, and you might have trouble keeping the printer set to the correct modes for each print request or using printer forms with the printer. In this case, you can either add an entry to terminfo for your printer or create a customized interface program to use with the printer.

Adding a printer entry to the terminfo database

To create a terminfo entry for your printer:

  1. Identify an entry in the /usr/lib/terminfo/terminfo.lp file that uses the same or similar commands as the printer you are adding and copy that information to filename, where filename is the file containing the terminfo entry you created for the printer.

  2. Use the information in the manual for your printer, ``terminfo entry definitions for printers'', and the terminfo(M) manual page to modify the entry in filename.

  3. Once you create the new entry, compile it into the database:

    tic filename

After adding or deleting terminfo entries or changing values that govern pitch settings, page width and length, or character sets, stop and restart the print service.
