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.....
