Hallo everyone, I'm sending this message (from Italy) because recently I've configured my Canon Pixma MX435 to use it in wi-fi mode in Arch Linux , actually my version in 6.4.11-arch2-1.
I use the sane-pixma backend and in order to use the printer via wi-fi I just added a line with its lan ip to /etc/sane.d/saned.conf; then i add a line with bjnp://printer-ip to /etc/sane.d/pixma.conf. I confirm the correct recognition and usage via wi-fi, so this model can be added to the list of the model working with sane-pixma. Thanks to all. Domenico Ritondale
