     This class is used to attach to a networked printer. You can also use this in order to attach to a printer that

+    If you have a local printer on parallel port ``/dev/usb/lp0`` then you could start ``socat`` with:

+    .. code-block:: none
+
+        socat -u TCP4-LISTEN:4242,reuseaddr,fork OPEN:/dev/usb/lp0
+
+    Then you should be able to attach to port ``4242`` with this class.
+    Otherwise the normal usecase would be to have a printer with ethernet interface. This type of printer should
+    work the same with this class. For the address of the printer check its manuals.
