Lines printed from PDF file opened in Adobe Reader are incorrect

[haylee18]

When printing a pdf file opened using Acrobat Reader DC, the lines came out wrong. My pdf file has dotted lines and straight lines (both line weights are at point 0.5), but after I print them, both the dotted and straight lines become thick and bold, as if the line weights have become point 2 or something, it no longer reflects the original design. I tested this on a different computer using Acrobat Reader DC, same thing, wrong lines.

I tried opening the same file on Microsoft Edge and print from there; the designs came out correct, no issues.
My version of Reader DC installed is  21.001.20145. 
Please help, thank you.

Hi

Scroll to the heading "Fix Hairlines" and see if this helps:

Set the unit to points, not inches.
