I have designed some PCB's with Proteus Ares 7.7 Sp2,i had used pic16f628A. But if i get output to printing, i see that there are dimension differences between real pic and my xps or pdf , there is %10 distortion. How can i solve this problem ?
You have to select "scaling: none" or "scaling: 100%" from your printing settings. Usually the default is something like "scaling: fit to page", and that usually shrinks the document when printing pdf files.
