+The Samsung SyncThru Printer platform allows you to read current data from your local Samsung printer.
+
+It usually provides information about the device's state, the left amount of ink or toner and the state of paper trays.
+The platform automatically monitors every supported part.
+
+If you wish not to include certain monitored values specify the values that you would like to see in the front-end via the `monitored_conditions` setting.
+
