Everything prints from Illustrator.
Looks like I got a grip in this.. turns out I have to use both print settings windows. The AR 1800 window would default to letter size each time. Print a 5" tall from AI and AR would give you an 11" piece of film plus the 2" for getting it out of the print zone. 1st I set the page and all sep settings in the AI window.. then click setup in the lower left and it takes you to the AR 1800 print settings, adjust page size via the advanced tab and keep hitting OK or print till you get back to AI print window and hit print.. vaa laa! now the standard feed between prints and no wasted film.
that did not work for me from what I can remember . . . AR was feeding extra sheet of film even on the test print from within the RIP.
