[sane-devel] Canon pixma MP160

[David Nicklay]

Hi,

All of the generation 2: CIS Canon Pixma printers seem to suffer from 
the same issue which seems to be a problem with the parameters passed to 
the printer.  aligning the pixels for the raw width to 16 for both gray 
and color seems to fix part of the problem, but I still cannot pass an 
arbirtrary offset x,y value.  This site has a patch for an MP600, which 
you need to use before anything will work:

http://pixma-mp600.sourceforge.jp/

 From the patch:
    /* Generation 2: CIS */
    DEVICE("Canon PIXMA MP160", MP160_PID, 600, PIXMA_CAP_EXPERIMENT),
    DEVICE("Canon PIXMA MP180", UNKNOWN_PID, 1200, PIXMA_CAP_EXPERIMENT),
    DEVICE("Canon PIXMA MP460", MP460_PID, 1200, 0),
    DEVICE("Canon PIXMA MP510", UNKNOWN_PID, 1200, PIXMA_CAP_EXPERIMENT),
    DEVICE("Canon PIXMA MP600", MP600_PID, 2400, 0),
    DEVICE("Canon PIXMA MP600R", UNKNOWN_PID, 2400, PIXMA_CAP_EXPERIMENT),

Any of these printers are probably affected.....
