I am using 24" roll and ADT 2004, I have the following questions: 1- what is the best paper size to use maximum space of the paper (for 24"X36" sheet). 2- I know that my pick points must be those two corners of that invisible 24"x36" rectangular but what would be my minimum margin that I have to set or consider?in other word what would be the size of the internal border inside the invisible 24"x36" border? Thanks, Afshin
