The wi-fi works very well; but had to fumble to turn: installation manual very basic (no text).
Also, go on the Canon site to recover the manual. It would be so easy to put it on the installation CD of Windows, for Mac users; which is my case. It should not be rocket science and expensive.
I had a PIXMA MP 640, which was more convenient and a lot less noisy and had their paper manual.
Average product, combining good printing qualities, but which has a few annoying flaws, particularly noise; it justified, therefore, to be preferred maybe another model.
Fast shipping within 3 days, no problem by Amazon.
