Samsung like other companies may have a new driver or a setting. In the USA I use 1800SAMSUNG. Or the chat at samsung.com. Other country? Samsung.com
My m2070w is giving me issues with wireless connectivity. When I install the driver on a pc/laptop it will initially function well, but after a random amount of time the printer will appear offline (in the samsung easy printer manager etc.) and no print will get through. Uninstalling then reinstalling the drivers was the only working solution so far, albeit a temporary one.
I use two w10 pro systems. I am fairly experienced in troubleshooting and working with computers, and after many days I failed to find a reasonable explanation as to what the problem is.
I look forward to finding a solution to this issue.
