Question: what paper should I buy for it?
Document: I had problems with this printer from the start. First I had difficulty getting it to feed paper. Once I could get it going, it worked okay until the next time. Now it doesn't feed at all. Authorized Canon service depots want a minimum of $85/hr even to look at it. I would not buy another one. Definitely gets no stars from me
I guided myself using the reviews here and convinced myself that this was a good printer. The price of this printer has dropped significantly since its release that makes it a better buy. If you want a good looking, compact printer that has wireless and battery capability this is certainly a contender. As for ink cartridges, yes, you can't buy them in shops but it is pretty straightforward to get them online.The biggest problem with this printer was that the paper jammed frequently and paper was nicked at the top.
I wanted a simple photo printer, just load 4x6 or 5x7 paper and print. This device could not meet those modest goals. It has been incredibly frustrating. It feeds paper through without printing. Prints one photo then refuses to print the next photo. Something inside spins, whirls, makes noise but paper won't feed. Steve Jobs set a high standard, consumer electronics should work, period. This printer does not and will be the last Canon printer I buy.
after 1.5 year of a good company, i am getting 3 flashing yellow lights which is ap paper jam. The printer doesnt work anymore. Now have to buy a new one or look somewere else. Or maybe it is a good idea to get extended warranty.Update: after cleaning color ink compartment on the printer light came off and it is working again. So do rating upgrade to 4 stars
I will buy a cheap Epson.
Since it is a portable printer I wish it was smaller other than that no issues. Need to buy the RF dongle
I couldn't be happier with the speed and quality in such a easily portable size. I would buy it again in a heartbeat!
What a piece of junk Canon is producing. I actually found an I90 on ebay and purchased that. Don't buy this junk!
It is definitely small but I need something 1/2 this size.Buy it! Its great. Service is brilliant
I also think that canon's customer service is excellent. I would buy it again even if I do miss my ip90.
Answer: If you are printing photos - you can buy photo quality paper.  I just use multipurpose white paper - its completely up to you!
