    Epson C65 ESC/P2 protocol

    There is lots of information about the ESC/P2 protocol within the GIMP-Print Developer's Manual which is also available as info files within the gimp-print distribution, e.g. as /usr/share/info/gimpprint.info-4.gz.

    The various status (ink level) and command (clean nozzle) ESC/P2 sequences are available using 'escputil'. 
    # escputil -q -i --new --raw-device /dev/usb/lp0 
           Ink color    Percent remaining
               Black     14
                Cyan      9
             Magenta      7
              Yellow     20
    But the status command doesn't look right (compare with this 
    [root@tower ink]# escputil -q -s -u -r /dev/usb/lp0
