Hi; This is a little complex to follow. It's taken me two weeks to define the problem without finding a solution. Basically, my HP psc_1310_series printer keeps becoming un-enabled and removed as default. Here is what happens: I login, check my printer_config settings and my HP psc_1310_series printer is check marked as enabled. Open a word processing or text editing program such as Open Office Writer, AbiWord, emacs or gedit and try and print a test page. The test page is put in the queue but no printing. I again check my printer_config; my HP psc_1310_series printer is no longer enabled. If I re-checkmark the enabled box and 'Apply', the printer immediately prints everything in the queue even if I have cancelled all the outstanding jobs. Everything continues to print fine in every program until I log out and in again. The cycle continues with the printer_config being marked as enabled until I call a new test print job. I am baffled. -- Regards Bill
