#627 Gutenprint 5.2.7, Canon MP250, grayscale?



Thanks very much for adding Canon MP250 support!

I have a problem with the driver, however. I need to print in Grayscale. But whenever I change any of the options like "Color Model" or "Resolution", it won't print.

Thanks for the help!


  • Hi,
    Sorry to have kept you waiting.
    I've examined the MP250 code and found that the command set had a mistake. I've corrected this in CVS. Do you have a chance to test CVS gutenprint? I'd like to know if grayscale works now or not.

    As I understand it, under resolution, you will see some modes with MONO in them: these are the grayscale modes you need to select. You also need to change the color model to grayscale (I think). Unfortunately, the current driver does not match modes and color models for you yet. For those printers where the same mode can print both in color and in grayscale, you only need to change the color model (and there will be no separate MONO modes in the resolution selection).

    I hope this explains the complication, which may have caused you trouble (apart from the error in the command set).

    Please let me know your thoughts and if you can test.
    Best regards,
    Gernot Hassenpflug
