I'm stumped trying to attain a certain effect in Microsoft Word 4.0 for the Mac. My company prints its manuals on ordinary 8 1/2 by 11 paper. We use a mirrored gutter on a landscape page. What we'd like to do is print each (odd or even) page *twice* on each page as it comes out of our PostScript printers, with an exact copy of the one page displaced to the right half. This way, we can easily give our printer these two-up masters, they can duplicate them double-sided, then cut them down the middle and out comes two perfect manuals, already collated. Am I missing something? Is there an easy way to do this two-up printing? Read action !
