Wifi problem: Unable to print using the wireless communication: the impression is first slow then stop, sometimes at 3/4 of the sheet; an error msg indicates the failure without explaining. I guess the wifi is not good enough (remote router) but no means of diagnosis or configuration of WiFi, the timeout for example. With a USB cable it works but I had to wait 8 days to receive the cable ordered together as the printer. I misjudged the clutter of the printer. Canon is careful to show the printer in real conditions, ie with the paper tray loaded: The tank must be empty to be closed. The initialization of the printer and printing the first page is (very) long. Painful when used in a timely manner. For print quality, I have not enough experience. A priori it is good.
