i am wanting to duplex on a canon clc4040 copier. ive created a pdf from an indd file. now the problem is is when i print from Acrobat 7 and try and duplex a 5 page document and select 2 copies it prints it fine. when i use acrobat 8 it prints on the back of the last page of the 1st copy of the document. seems like the rip is seeing it as 1 copy of 10 pages instead of 2 copies of 5 pages. this only happens in ver. 8. any1 got a work around for this? i'd greatly appreciate your feedback.
