I have just bought a TS9550 all in one printer scanner. This was to replace an MG6850 that broke. It has taken a day and a half now before I got it anywhere near setup. The cd that came with it had a tick box, already ticked, that said tick to use latest drivers from the internet. In the second day of fruitless attempts I unticked this box and the setup went through in about five minutes. I had been directed to a tech support the previous day who just kept on showing me Youtube videos that didn't help me, and I was charged for this service, thanks Canon.
