I sincerely hope you can help. I have a Canon Pixma Mg3550 and it is the worst printer, well piece of technology even, I have ever encountered.
Nearly every time I try to print something it either just doesn't print, sitting there with no messages or warnings, it just does nothing, or it takes the paper in and prints a few lines and then stops, waits a few seconds before spitting the paper out unfinished.
I know the wifi signal at this end of the house isn't great, but it even does this with the booster and when I moved the router into the hallway opposite the door to the office.
We bought a cable to connect it to the PC via the USB port, when it prints through this it works fine, but to get it to work through this I have to download and reinstall the driver for this from their website every time I turn the computer off. If I turn the computer off and then come to print something a day or two later, it just automatically prefers the wifi connection and the only way I can find to stop it using it is to download the drivers from the canon website.
Does anyone know how I can permanently disable the wifi connection on this printer? I'm running Windows 10 if that helps.
