You can optionally set the default system paper size in the file /etc/papersize. This default is used by SavaPage, but can again be overridden in the Admin Web App. See Section 4.11.13.6, “Default Paper Size”.

The format of the /etc/papersize file is very simple: whitespace and anything starting with “#” is ignored, and the name of the paper is the first string found; the case in the name of the paper is irrelevant. Commonly valid paper size values are: a3, a4, a5, b5, letter, legal, executive, note and 11x17.

For example, use this command to set the default to a4:

sudo su -c 'echo a4 > /etc/papersize'
