Our website generates Word 2007 documents from database data by creating the xml, zipping it and sending it as a MIME attachment. Usually, this works fine. On occasion, the document will look fine on the screen, but not when printed. The letters end up scrunched together.

Here is an example. This is a 1 page document, the first page is a scan of the document printed correctly, the 2nd page is a scan of the same document printed with the problem.

Here is the original document.

Has anyone ever seen anything similar? I cannot figure out if this is a bug in the code that generates our XML, a bug in the printer driver or a bug in Word. Any ideas would be greatly appreciated.
