Samsung SCX - 3400 series
I am unable to use the printer. I followed the instructions in the below thread. Scanner is working but the printer is not.
MacBook Air (2020 or later)
Thank you. The Samsung SCX-3406W is listed as HP SCX-3406W in About AirPrint - Apple Support as a model supporting the driverless AirPrint technology. You should be able to use the printer without having to install any drivers, provided that the SCX-3406W and your Mac are connected to the same network/Wi-Fi router.
Have you tried an AirPrint connection, or did you make an attempt to use a universal driver with USB?
Also, have you checked whether the latest printer firmware is installed? You could possibly check firmware updates/upgrades via the SyncThru Web Service Maintenance tab. See page 272 in the manual at http://h10032.www1.hp.com/ctg/Manual/c05786719.pdf#G14.4944743 . Make absolutely sure that any downloaded firmware files are intended for your exact printer model.
