[cad123]

I have problem with print a drawing to plotter HP750C.When I plot a A3 size drawing and 2 copies, the plotter only print seperate drawing( the 1st and next is the 2nd)but waste more blank paper.
How can I set up print 2 copies in one times(save paper and time) ?
Please help me.

If I understand the question clearly, I would open the dwg you want two copies of, copy all entities and stack the drawing so you have two drawings in one. plot on one large sheet and trim. Of course, do not save changes.
