Question about Canon PIXMA MP780 All-In-One InkJet Printer
Did you make sure you installed it off of a cd or have all the latest drivers if none of those works just reinstall if you can and see if that works

Chek the product registration code online ,check the network port and IP addresss and try to add IP address of printer manually ,if this also not works , try to restart printer than do the same process
