I'm sure you've figured this out since, but I thought I'd post in case someone stumbles upon this (like I did) but gets nowhere.
I messed with the settings the other respondant suggested but it did not fix my problem. I figured it out:
When you go to print, and BEFORE you actually print, go to "Page Settings" (NOT "Printer Preferences"). From there, click on the "Paper" tab. Select "Tray 1" in both boxes and click "Okay." It may say some nonsense about margins - just say yes/okay or even fix. Also, you can set it as a default here. Make sure you save the document as I think this saves the default as well.
I hope this helps... (does my work REALLY use a printer from 2009??)
