Got a brand new unopened Epson XP-4100 that I have found out apparently doesn't have a "Thick Paper" setting? I need to print museum quality 53 lb. and 67 lb. card stock prints all the time and I am thinking that if I choose "Envelope" on the control panel in place of the missing "Thick Paper" setting that it might do the trick? By do the trick I mean not smudge and/or spill ink and make a big mess? Jobs would be sent from comp. running OSX. If that don't work I'll have to continue hunting for another printer? What do you think?
