I have about half of my iPrint printers showing Printer State: Stopped.

I have restarted the print server, then physically restarted the printer, the iPrint services on OES2 Linux, and finally restarted the entire Linux box. I still get the same message and no one can print to those printers.

The printers are HPs and Lexmarks. Anyone have an idea? It was working fine until today. Nothing has been changed on the server recently...upgraded java to 1.5 sr8 within the last four weeks.
