The system PAPERSIZE is usually set when installing and updating an Ubuntu system using PAPERCONFIG. If the papersize file does not exist, programs using the paper library default to using letter as a fall-back value. Permitted papersize values include a3 a4 a5 b5 letter legal executive note and 11×17. When the default papersize is changed using paperconfig, it notifies other packages of the change by running the scripts in the /etc/libpaper.d directory if any. My system has none. When I upgraded to Ubuntu 12.04 my PAPERSIZE was changed to LETTER and LibO kept defaulting to LETTER. It took me a while to find the problem. Likewise my American netbook was initially set to letter although my printer was A4. What caused the problem I don't know. However, the software needs to check the PAPERSIZE file on startup or installation. LibO seems to do this, not certain about PDF reader. One symptom of a paper size mismatch (A4 thinks it is letter) can be a blank sheet of paper ejected after the printed page. Printing has always been a dark art. My wife has a special requirement only available in letter size which keeps me on my toes.
