  1. I followed your instructions exactly and removed the printer. Now my computer can find the scanner which is on top of the Canon MG5220, but it cannot refind the printer to add when I hit +. It only finds me an additional scanner.

  2. I have followed your instruction but i still have the error, and I can't print nothing. What's weir it is that until this evening it worked perfectly well. I am on this since 2 hours and can't find any solution. thank you for your help

  3. The versions created by 3D laser printers are much less expensive in contrast to models constructed by various other methods. 3d printing

  4. I've been getting this 306 error in the past few days, and the beauty of it is my printer Canon Pixma is not wifi, but connected via USB.
    I've tried unistalling and reinstalling. It's always worked well until now. Any suggestions?
