+Labels for multi-step
+---------------------
+
+For companies using :doc:`two <../daily_operations/receipts_delivery_two_steps>` or :doc:`three step
+delivery <../daily_operations/delivery_three_steps>`, labels can be triggered to print after
+validating the picking or packing operation. To do that, go to :menuselection:`Inventory app -->
+Configuration --> Operations Types`, and choose the desired operation.
+
+On the :guilabel:`Operation Type` configuration page, tick the :guilabel:`Print Label` checkbox.
+Enabling this feature ensures that the third-party shipping label is printed upon validating this
+operation.
+
+.. example::
+   For :doc:`two-step delivery <../daily_operations/receipts_delivery_two_steps>`, where products
+   are placed directly in packages during picking, companies can print shipping labels during
+   picking instead of delivery. Odoo allows users to enable the :guilabel:`Print Label` feature on
+   the `Pick` operation itself to achieve this flexibility.

 Print tracking labels
 =====================
 
-Tracking labels are generated after the delivery order (DO) is validated.
+Tracking labels are printed when specific operations are validated. By default, validating a
+delivery order (DO) generates a tracking label in the chatter.

+.. note::
+   For companies using two or three step delivery, refer to the :ref:`printing labels for multi-step
+   delivery <inventory/shipping_receiving/picking-config>` section to learn how to print the label
+   after validating a picking or packing operation.
