Microsoft PDF Won't Print Some Letters

[printchesco]

I think this happens when the application does not contain the fonts that are in the document. Try printing the pdf as an image.

Search for this problem on internet showed many hits dealing with the same issue. Sometimes the software that creates the PDF doesn't embed the fonts used in the doc so printer tries to substitute. If it can't find a substitute the printer just skips it. This could be what is causing it. The other thing I saw a lot of people suggest is to make sure the printer drivers are up-to-date by the manufacturer. Don't really understand all the technical stuff, but it appears you are not alone out there.
