MG3530 wireless printer is useless
The paper jam is so bad that it is very difficult to use. Even when I pressed the print button, I said that I was asleep, saying "The other computer is using the printer."
This is a Canon printer. Canon quality.
It took 30 minutes or more to print 5 sheets. I am frustrated after passing through the frustration. If you don't want to feel unpleasant, you should buy a printer from another company.
