I used to run LM 13 and the built in driver for my Epson NX430 printed just fine over WiFi.
I wiped and installed LM 14 and although black printing (text) is crisp, colors are all out of phase. You can see the individual inks separately because they aren't laid on top of each other to create the final intended color. Each color is printed on a different spot on the paper. Also the printing is very slow, the test page takes 2 min to finish.
I confirmed with a WiFi Windows laptop and a Windows desktop that the printer is fine.
I also went to the Epson web site and downloaded the latest "full featured" Linux driver and installed the DEB package, but it doesn't seem to have made any difference. I also don't see any "features" when I look at the Printer properties. Maybe I didn't do everything necessary to actually update the driver? Is it possible to install the software package but not update the driver? I am new to Linux.
