Step 4 - Optional System Settings
---------------------------------

.. _ch-install-optional-system-settings-paper-size:

Set Default Paper Size
~~~~~~~~~~~~~~~~~~~~~~

You can optionally set the default system paper size in the file
``/etc/papersize``. This default is used by |PRODUCT_NAME|, but can again
be overridden in the Admin Web App. 
See :ref:`Default Paper Size <ch-webapp-admin-options-advanced-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``:

.. code-block:: bash

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