Hi Jef and thanks for the fast reply. The printout looks fine. It is printed with 100%, though, so that was to be expected.
I use the current Acrobat Reader to view my files and I have commercial Documents, with graphics that look great no matter how large I scale, so it can not really be the viewer?
