tion using one of the following methods:

• On the GNOME desktop, go to the Main Menu Button (on the Panel) => Programs =>

System => redhat-switch-printer.

• On the KDE desktop, go to the Main Menu Button (on the Panel) => System => redhat-

switch-printer.

• Type the command redhat-switch-printer at a shell prompt (for example, in an XTerm

or GNOME terminal).

The program automatically detect if the X Window System is running. If it is running, the

program starts in graphical mode as shown in Figure 21-17. If X is not detected, it starts in
