m2070 Samsung printer won't print duplex
Hey everybody,
I just installed the Samsung Printer M2070W, now the option "Manually Duplex" is not active, just grey.
I heard this is a common problem, options I found didn't work for me...
Any ideas please?! I know this printer should be able to do it, in windows it does work! Probably a driver/software problem!
Please help
