I have windows 8 and an epson workforce 520. I cannot get it online. I have 10 items in to be printed buy it says the printer is offline.
I have windows 8.1 and the same problem.
If windows 8.1 discovers the printer is off OR ON STANDBY, it never-ever-never checks it again!
It takes a reboot to get it to see the printer is on.
You screwed the pooch bad, Microsoft! Windows 8.1 will not kick the printer from Standby. all the other windows since 64-bit XP did just fine!
