10.1 How can I ensure that all programs use the same paper size?
Install the libpaper1 package, and it will ask you for a
system-wide default paper size. This setting will be kept in the file
/etc/papersize.
Users can override the paper size setting using the PAPERSIZE
environment variable. For details, see the manual page
papersize(5).
