After receiving updates for this epson xp-420 printer it would no longer communicate with my macbook air. I spent over 3 hours trying to figure out the problem, even starting from scratch. It went so far as to print out one page declaring the connection with my wifi was complete and then nothing! I tried to print a recipe from my mac and the pages came out blank...yes, I had plenty of ink. I went to Best Buy where I purchased this Epson and even the sales clerk (who happened to have the same xp-420 at home) said he got so tired of trying to fix his that he had to hardwire it with usb cable. The final outcome? I just bought a Brother printer/scanner to replace this epson piece of junk.
