"Printer disabled" - how to prevent it?

[sevans at rutherfordglobal.com]

I have the exact same problem anyone have a solution?

> Several times a week one of my printers gets "disabled" by CUPS, and printing doesn't work anymore until I manually "enable" this printer. It happens both with USB and network printers. I'm running CUPS 1.1.23, but the problem also happened with earlier versions of CUPS.
