           Summary: Wrong line width when printed to PDF
    Classification: Unclassified
           Product: WebKit
           Version: Safari 9
          Hardware: Unspecified
                OS: OS X 10.11
            Status: NEW
          Severity: Normal
          Priority: P2

Created attachment 285526
  --> https://bugs.webkit.org/attachment.cgi?id=285526&action=review
all three examples

Line widths are not printed correctly to PDF. I have thought that is a problem of Apples "Quartz PDFContext" but printed with Word, fine lines are printed exactly.
HTML lines in Safari are not, whereas SVG lines are printed correctly. So maybe its a Safari/Webkit problem.
Behaviour: lines thinner than 1px are not printed, with 1px they are printed with a width of 2px, not very nice when 2px is the result of a wanted hairline!

I attached a Word, HTML and SVG PDF-example.

This problem persists for years even in OS 10.11.6.
