HP LaserJet is printing gibberish

Hi there
We have a new HP Color LaserJet CP2025 which was printing fine for a few days but now there is an issue with printing some docs. Not all are affected but some are printing out as gibberish - they look fine on screen but print out as symbols ($%!"). Is there a setting that needs changing?
Thanks

Try selecting all the text and changing the font. We've had this problem and doing that seems to sort it.
