    I have an Epson Stylus Color 860 (locally attached USB). A cups
    print job was spooled, but the printer is stalled in an out-of-ink condition.

    Cups let me cancel the print job, but the underlying usb process
    is hung (even kill -KILL doesn't relese it).

      root 8587 8571 0 21:03 ? 00:00:29 usb:/dev/usb/lp0 74 xxxx (stdin)

    lsof shows this process has /dev/usb/lp0 opened and the kernel
    module usblp.ko reports it's in use and can not be unloaded.

    Can this condition be fixed without a reboot? Is there anything
    I can do to gather more information?

    BTW, this is kernel 2.6.10-1.760_FC3
