I have same problem for nearly two months now.
I do not think that this is a microsoft problem.
Each morning, I send out an email message to a group of people and I send a copy of my sent emails to EpsonConnect (my printer's email address) which then goes to cyberworld at Epson, which sends a copy of the email back directly, via wifi from my router, to the printer, which then puts the heading:
Get/eSCL/ScannerStatus HTTP/1.1 Host: local host.
So, this doesn't have anything to do with my PC, Windows or Microsoft. It's an Epson printer problem.
However... I also get the weird headings when printing directly from my PC.
I'll keep bugging Epson.
