I have been printing envelopes via MS Word 2010 for quite some time. I made the mistake of looking at the envelope templates (to add a little decor to the envelopes)
Now when I try to print an envelope in the basic template (no extras, just the return / sender's address), the envelope basically comes up blank when printed. If I try to print one of the envelope templates, they don't print correctly either.
I have enlosed some screen shots. I am using HP2840 All in One and connected through a network.
