What does the Epson windows driver Version Information >> Client Settings >> "Share Network User Settings" setting do?
By context I would think this means page sizes & colour configurations etc. could be shared to and used by other people, but this isn't happening for us (and/or I don't see how access it).
The phrases "Share Network User Settings", "User Settings" & "Share Network" do not appear in the manuals (500+ pages) and shorter combinations have too many results (though I'm still looking through them).
