Chapter 26. Printer Configuration

The Printer Configuration Tool allows users to configure a printer. This tool helps maintain the printer configuration file, print spool directories, and print filters.

Red Hat Enterprise Linux 4 uses the CUPS printing system. If a system was upgraded from a previous Red Hat Enterprise Linux version that used CUPS, the upgrade process preserved the configured queues.

Using the Printer Configuration Tool requires root privileges. To start the application, select Applications (the main menu on the panel) => System Settings => Printing, or type the command system-config-printer. This command automatically determines whether to run the graphical or text-based version depending on whether the command is executed in the graphical desktop environment or from a text-based console.

To force the Printer Configuration Tool to run as a text-based application, execute the command system-config-printer-tui from a shell prompt.

ImportantImportant
 

Do not edit the /etc/printcap file or the files in the /etc/cups/ directory. Each time the printer daemon (cups) is started or restarted, new configuration files are dynamically created. The files are dynamically created when changes are applied with the Printer Configuration Tool as well.

The following types of print queues can be configured:

ImportantImportant
 

If you add a new print queue or modify an existing one, you must apply the changes for them to take effect.

Clicking the Apply button saves any changes that you have made and restarts the printer daemon. The changes are not written to the configuration file until the printer daemon is restarted. Alternatively, you can choose Action => Apply.

26.1. Adding a Local Printer

To add a local printer, such as one attached through a parallel port or USB port on your computer, click the New button in the main Printer Configuration Tool window to display the window in Figure 26-2. Click Forward to proceed.

Figure 26-2. Adding a Printer

In the window shown in Figure 26-3, enter a unique name for the printer in the Name text field. The printer name cannot contain spaces and must begin with a letter. The printer name may contain letters, numbers, dashes (-), and underscores (_). Optionally, enter a short description for the printer, which can contain spaces.

Figure 26-3. Selecting a Queue Name

After clicking Forward, Figure 26-4 appears. Select Locally-connected from the Select a queue type menu, and select the device. The device is usually /dev/lp0 for a parallel printer or /dev/usb/lp0 for a USB printer. If no devices appear in the list, click Rescan devices to rescan the computer or click Custom device to specify it manually. Click Forward to continue.
