I have the same issue - the cause? Google Cloud Print service.
To fix head to this URL - https://www.google.com/cloudprint/#printers
Select your printer and click Delete.
Google and Epson have been made aware of this issue, and are both working to fix (source: https://productforums.google.com/forum/#!topic/chromebook-central/525W6rnP5Dc)
