Just got an Epson B-310 with a duplex attachment. Trying to print a test 8 page booklet. Pages are 5.5"x8.5" for folded letter size paper. If duplex is off, all text is positioned correctly (centered on the page). If I duplex with the first landscape mode, the second set of pages printed on the back side (pages 2,7 and 4,5) are shifted to the right 0.5". If I use the second landscape mode (reversing the print) the second set of pages is shifted left 0.5". Any ideas on what setting I am missing? Epson basically says "Since we don't support Adobe InDesign I'm not sure what settings to tell you to select or change for the margin setup you desire." I hope it is just a setting I have not found yet. The previews look correct. The print is shifted on the pages coming out of the duplexor.
