From Drafsight V1R5.2 x64, I am able to print my drawing to scale to a laser printer accurately from Model view, using 1:1 scale, current view and print on center of paper.  When I export to PDF, then print to the same printer using Adobe Acrobat XI Pro, the same drawing is not to 1:1 scale. I have ensured that I am selecting Actual Size when printing.  When I use the Print function and then select PDF instead of my printer, the drawing comes out closer but is not 1:1.  Can anyone offer any suggestions?

Thanks!
