system-config-printer
 

What dose this mean or whats wrong? How can I fix it?

Thanks

Do you have pygtk package installed ?

I install pkgtk but now.

Yeah figures.
You are trying to run Redhat's printer configuration applet, but since Redhat uses Gnome you will probably have to install a lot of Gnome as well.
Why do you want this applet in the first place? It is not going to work in a Slackware box anyway.

Wait... From which package have you system-config-printer installed ?
Is it a gnome (god forbid) software ? :)

Have you tried: http://localhost:631 to set your printer ?

Alien Bob: I'm using Xfce and want to be able to print.

keefaz: I try http://localhost:631/ and here what I got "404 Not Found".

Have you started the CUPS service? From the command line try the following:

chmod +x /etc/rc.d/rc.cups
/etc/rc.d/rc.cups start

Also, if you don't mind temporarily using KDE, the Control Center provides a nice GUI interface to configure printers. Similar to the CUPS web interface.

As Woodsman already said, the error "404 Not Found" at http://localhost:631/ means that your cups service is not starting at boot. He also showed you what commands to use so that the CUPS printing service will start on every boot.

See here for configuring your printing in XFCE: http://www.xfce.org/documentation/4.2/manuals/xfprint Pich "CUPS" as the print service type available to you.
