Tips and/or tricks to print conversations?

I know how to print a conversation. That isn't what I am asking.

When I print a conversation to pdf, it get's all screwed up and loses or obscures text horribly. Mostly like it has a footer that is masking the text so some is lost. I've tried changing the printer margins and turning footers/headers off but can't seem to get it come out cleanly. Add that sometimes pictures shift around and sometimes are over the top of the text. Very frustrating.

Any ideas on how to print a conversation without those issues? I've tried different printers and nothing seems to change it.

Like to keep a copy of a conversation and can't get a good copy.
