Have you tried selecting "print as image" in the print menu?
Yes I did... It still doesn't print the document properly.. Since I needed those documents as soon as possible, I downloaded another software which printed my document with no mistakes...
However I still want to find a solution for the problem with Adobe Reader.
It could be that the fonts in the document have not been embedded properly so your system is substituting them for something else (it doesn't always do a good job as you can see).
You can check that by going to Flie>Properties>Fonts. You should see "embedded" or "embedded subset" next to the font names. If not then, that's the problem and there's nothing you can really do about it short of contacting the creator of the file and asking them to embed the fonts.
