Hello Katie,
Well, I've done just as you have suggested, and no luck! It still spools out the extra foot of paper. It seems to be linked to the custom paper size, as I tried printing the file out of pre-set size ANSI D, and it didn't print out the extra paper. (However, our margins don't work with ANSI D and we have used the custom size of 22W and 35H with a 270 Rotation set on the plotter. Our margins are .25 Left and Right, .68 Top and Bottom. ) I've tried deleting and then recreating the custom paper size...no luck either!
