Samsung Laser Printer M2020W not compatible with Big Sur
Can only get printer to work via USB but need it run wirelessly. Tried everything I can think of.
Mac mini 2018 or later
Question marked as
The only HP driver for the Samsung Xpress SL M2020W laser was for Catalina and released in Sept 2020. It would be a 64-bit driver, but due to the release date, could not have been tested with a released version of Big Sur. If you installed that driver, and still cannot print wirelessly, then you are done with HP as a driver source. You might contact them about plans for Big Sur support.
This particular device is not shown as supported in Apple's built-in AirPrint.
