I have the same issue with Firefox, Thunderbird and OpenOffice. When we print we have to manually change from letter to a4 ...
I print through a server using the ipp protocol with cups. The file /etc/papersize is set to a4 both in the server and in the client (both ubuntu gusty up to date). I manage the printer with the web interface and the default paper is correctly set to a4. Also, on the client in "System, Administration, Printing" I set the default paper size on a4.
