Cannot print anymore since upgrade to Macos 10.13.6
I had kind of the same issue with an epson printer, and I tried several times to make it work by downloading driver from different websites with non results. The solution is downloading even an "old" drive from the apple support website https://support.apple.com/downloads/drivers and It really does work. I wasn't really sure at first because it didn't said that support Mac Sierra but in the end it worked perfectly!!!
