I can fully support this request. I had an Epson Stylus Office BX625FWD working completely fine under El Capitan with Image Capture Application drivers and WiFi and it also worked for some time after upgrading to Sierra but then suddenly stopped. I first removed the printer and tried to re-install it but then noticed that the printer was "only" recognized as "Bonjour" and not "Bonjour Multifunction". So I removed all drivers, reset the printer system and killed PRAM. After that I could install the printer properly and it worked for a week or so. Then for whatever reason, it stopped working again, so I removed the printer again, removed all drivers and killed PRAM but then, no success. So - as the printer was 6 years old and the drivers might not get updated anymore - I decided to buy a NEW Epson WorkForce WF-3620DWF and installed all software bundles and whohooo... it was recognized correctly as "Bonjour Multifunction" and I could scan once with Image Capture Application drivers. ONCE! After that same problem again! BUT I could print using Epson Scan software - using TWAIN - ALL THE TIME! So there must be a problem with those ICA drivers and Bonjour Multifunction!
