Comment 12 for bug 1412729

I confirm it works.

I already had my wireless Epson printer setup in Ubuntu, so I removed it from the settings, uninstalled the driver package and removed the Epson repository.
Then I upgraded the 4 packages built by system-config-printer to the version in trusty-proposed and tried to add the printer. It worked correctly and the printer is working (again).
But, since the printer was already installed, the result may not have been accurate (even though I uninstalled it before testing).
