>>>I am getting an error on my clients site when I use the PrintOut Method to print my document in Word. It gives me a "OLE - type mismatch" error. The code runs fine on my system at home where I test but gives me this error at my clients site. Does anyone have a clue why I am getting this error?

It does sound like Carlos had a good idea - slightly different versions of Office. Can you run this command as a macro inside Word at the client's site?
