Printing Mail pdf attachments


I am new to AppleScript and want to use a Mail rule to run an AppleScript that prints a pdf received as an attachment to an email. This is what I have got so far…

on perform_mail_action(info)
tell application “Mail”
set selectedMessages to |SelectedMessages| of info
repeat with eachMessage in selectedMessages
set thePDF to (mail attachment of eachMessage)
save thePDF as “:temp.pdf”

		tell application "Finder"
			print thePDF
			delete thePDF
		end tell
	end repeat
end tell

end perform_mail_action

This doesn’t actually work but hopefully is heading in the right direction. I f anybody could give some help that would be much appreciated, I have ground to a halt.
