It used to be that you could get selection boxes of several different brands/grades of paper for a nominal sum. Worthwhile if they are still available. I think Jessops did them and also Dixons (?!?!?!?!) - shops, don't know about online.
It is said though that best results are from the paper designed for the printer and I have to state that in the case of my Epson, it is substantially true.
Don't know 'bout Canon, but the HPs I've used give the best results with Ilford papers, especially Ilford Classic Pearl. One nice thing about Classic Pearl, it can be printed on the back, this way rejects can be used for test prints. Another is that it is great for B/w prints, no colour cast of its own.
I have the same printer and Canon paper does give excellent results. I have a selection of papers that do also give excellent results. I recently got a new Fuji paper from click here (very good prices) and this also gives superb prints - and dries almost instantly. I have also used Ilford and Xerox and have been pleased with them. I try to pick up good quality paper on offer in places like Staples when I can.
The Canon claim of 20 years without fade with their inks is hard to verify, but I tend to use it for prints I want to keep or display.
The general rule seems to be that expensive paper gives better reults. I do sample prints because there are slight variations in colour with the different papers.
