------------------------

GNU/Linux supports native printing through the Common UNIX Printing
System (CUPS) and Internet Printing Protocol (IPP).

     - If :ref:`SavaPage IPP Everywhere <ch-printer-ipp-everywhere>`
       is configured in a Local Network, the corresponding printer
       is automatically detected by CUPS 2.2.2 (or later) and can
       directly be used without any configuration. |br| 
       |br|
       In older CUPS versions the SavaPage IPP Everywhere printer is recognized 
       as “Network Printer”, but you must choose a driver either from the database
       (Generic > Generic PostScript Printer Foomatic) or provide a PPD file,
       i.e. ``SAVAPAGE.ppd``. |br| 
       |br|

       - :ref:`IP Based Authentication <ch-auth-ip-based>` or :ref:`Basic Authentication <ch-auth-basic>`
         is needed before submitting a print job.

   * - |image64|
     - You can add any SavaPage Local IPP Printer according to the
       :ref:`SavaPage Printer URI syntax <app-url-printers>`. For example: |br| 
       |br|
       
       -  Choose a driver either from the database (Generic > Generic
          PostScript Printer Foomatic) or provide a PPD file, i.e. 
          ``SAVAPAGE.ppd``.
       - Enter ``ipps://savapage:8632/printers`` at **Device URI**
         for the default queue, or ``ipps://savapage:8632/printers/[queue]``
         for any other specific queue.

       Notes: |br|

       -  :ref:`IP Based Authentication <ch-auth-ip-based>` or 
          :ref:`Basic Authentication <ch-auth-basic>` might be
          needed before submitting a print job.
       -  For Internet Printer settings, see :ref:`Internet
          Printer <ch-webapp-user-main-user-details-internet-printer>`
          (no additional authentication is needed).
