A:AnswerI mainly use this printer for the photos, if the spec said it can print out the B size, then it should be. The photo prints are excellent.
Sorry for not helping you. Call Canon directly and ask for it before you buy the product.
Thank you.
A:AnswerYes, the printer is compatible with Windows 7. I am running Windows 7 64 bit. The only problem I had was setting it up wireless, I used the second wireless option and it worked.
