Are there Intellicad print drivers vs. ACAD? I have print pr

#1
My dropdown in PRINT SETUP doesn't list 24x36 for my Designjet 100, although it does list 22x34. So I drill down to where I can select 24x36 but by the time I get back to the PRINT SETUP screen it says 8.5x11 and still doesn't list 24x36 in the dropdown menu. However when I hit OK and am back at the PRINT menu it says 24x36 and will sometime print at that scale. If I try PRINT PREVIEW it reverts to 8.5 x 11 and I have to drill back down and change it back to 24x36.

Anyway my DJ 100 came with ACAD drivers which I installed. My computer automatically installed the DJ drivers.

Do I need drivers specific to Intellicad?
