Hello, my printer model is G3000. I connected it to my MacBook by wireless connection. After updating the macOS Sierra (10.12), I cannot print things out and something like "cannot connect the printer" always shows up. So I reset the printing system in my macbook and try to set up the printer again. It connected successfully while using USB connection, but the macbook cannot detect the printer when I try to use to wireless LAN connection. Does anyone know how to solve the problem? 😞 Lots of thanks:(
