****Urgent -- I had been trying to fix my problem of my Canon MX 850 not working on my network, for quite awhile. It wasn't recognizing it suddenly. Nothing I tried or read online worked EXCEPT FOR THE ABOVE ADVICE FROM KEGOBEER. I was this close to going out and buying a new printer, even though mine wasn't that old. As I was about to go out the door I said, let me look one more time on the internet for an answer, even though I thought I had tried everything. I came across this post and IT WORKED!!!!!!!!!!!!!!!!!!!!!! Thank you whomever you are, and anyone with a similar problem, please heed this individual's advise.
