Could you describe what you'd like to accomplish and what you tried to do?

Does your printer work with other software?

What OS and Thunderbird versions are you using?

i try to filtering my email with massage filter, like if new email coming from email or subject.... than print it, and I already install add on print it, and i try with window vista and window xp both doesn't work.

and my printer is working correctly, i can print from TB and hit print, and everything is ok, but i need print automatically if once email coming from someone was on my massage filter than print it

What Thunderbird version are you using?

You mention "I already install add on print it", which add-on is this?
