Summary: Easy enough to set up.....hard to find ink cartridges for it once it's over 6 months old. Have to go to re-manufactured ones that don't break the bank. The picture quality is ok....but I guess I got what I paid for. And I am a BIG fan of Canon Cameras and lenses. This is why I was disappointed. Sorry.
Summary: Nice attractive printer/scanner/copier. Reasonably compact, handsome, if slightly fragile finish. Clear LCD screen that can be positioned for several different viewing angles - convenient. Bought it for my 88 year old mother's use and she caught on to it pretty quickly and found that she could make copies of organ music saving a trip to the library (this ignores the social component of the library and the savings maybe illusory).
Summary: I gave trying to get the scanner working on the HP 8500 I have. Bought this instead. Set up the printer and computer with USB cable. Then did firmware update on the printer. No issues with using scanner now. The HP is being used for wireless printing only. I have gone through the install and set up for the HP a few times and the Canon set up is simplier and easier to follow.
Summary: the printer is mainly used for resumes, essays and photos. It works wonderful for all our printing needs in a timely manner. The only slight issue I have with this printer is when My DH's computer is off or sleeping I cannot print from my laptop. I have to turn on his computer (the main computer) first before I print from my laptop.
Summary: I bought this printer for everyday printing. So far, I've mostly used it just for documents, but I've printed a couple pictures as well. Wifi setup was easy, and means that I can put it anywhere in my house without having o route any cables. Printing is decently fast, and quality seems good, but I haven't tried any really high-quality pictures. The controls on the printer are a little clumsy, but overall it works well.
Summary: This is a very decent printer for the price. The set-up is quick and relatively easy (just follow the instructions on your screen carefully). Here is a hint: if you use wireless connection, and your computer says the printer is offline (while connected to the access point), turn off the router and turn it back on again (it will save you 30 min on the phone with Canon customer service, which, by the way, is exceptional).
Summary: I purchased the Canon MG 4120 inkjet printer from Amazon.com for use in my RV. I needed an all-in-one printer with a small footprint that could be carefully transported for use travelling. Based upon my experience with Canon prducts and input from other sources I purchased the Canon MG 4120. To my dismay after printing just 10 copies my printer developed a "phantom" paper jam error that I could not clear even though there was no paper or other object in the printer.
