I’ve got 2 printers, an HP and a Samsung ML1660. The HP works fine, and the Samsung loads in printers but has a pause symbol on it, because it isn’t enabled. If I click on “enable printer” in the right-click menu, it goes away for about 10 seconds then comes back. I’m at a loss as to what’s going on here. I have tried reinstalling the printer from CUPS web interface and the system dialog(see below).
Also (might be a bug): removing the printer and reinstalling using the system dialog causes the dialog to freeze and not respond.
