Dear all, I am happy to state that the Canon MP450 works perfectly with the CVs pixma backend, in color & greyscale (there is no native lineart mode) from 75dpi through to 1200dpi. Support can therefore be changed to complete in the backend.
I will send diffs to Nicolas when we discuss changes I have made to the backend, in September. Regards, Gernot -- ISP Asahi-Net: http://asahi-net.jp/en/ No.1 in Japan by customer satisfaction (Nikkei News, 7 July 2010)
