I have a little problem with printing pdf-ducuments with Acrobat Reader 7.0
If I open a document in the browser (Firefox) and then print the document, the first few pages were printed correct, but after a while only cryptic text is coming out of the printer. the letters were jumbled and the document is unreadable.
If I save the document on harddisk, printing is possible without errors.
Sounds like a printer driver issue with FireFox to me. Try using IE to see if you have the same problem or not. If not, then you can pretty sure that there is a compatible issue of your printer driver with FireFox. Also, which FireFox version you are using?
