Comment 94 for bug 35638

Have this identical problem but being a nube have no real clue how to address.

From above:
"On my R51 connected to the Laserjet4 running WindowsXP, I had to tell
Windows to use the USB port to find the Printer, it does that and works.
That could be a way to fix it with Linux CUPS."

I have same condition except:
Windows 2K, processor self assembled (INTELD865PERL MB/1.5GB)
LJ4 on Parallel to USB cable
HP 890c Deskjet on same cable type.

My Ubuntu system is Gutsy. (7.10)

HP 890c never (well almost never) fails to identify and jobs will follow it if usb cable is moved to another usb port.
HP LJ4 almost never identifies.

W2k is rock solid on both printers using these cables so the cables must be passing device ids. Up to now Ive not found many things Windoze can do the Ubuntu could not. This appears to be one of those more noticeable problems.
Sometimes a reboot will find the HP4 but usually not. Once found it can be added and functions until a reboot.
Have never seen it drop once found until the system is rebooted. Then it will show in the installed printers list but will not print.

If this is a bug that has been opened www.cups.org can you point me to the bug report and I'll follow it there.
Thanks,
Bill
