I am trying to create a new label format in my Odoo v.16 online version.

I would like this option format to appear as an option when I use the "print labels" (action_open_label_layout) button.

From what I learned I need some python code for that and so I created everything by a custom module.

In the module I define:

  • the new paper format (as record)
  • 2 actions to open the report from product.product and product.template (as records)
  • 3 views (as templates)
    • 1 view for the label desing
    • 1 view that hands over data if triggered by action of product.product
    • 1 view that hands over data if triggered by action of product.template
  • 1 python code model to add the new report as print_format

The module is successfully imported. Paper format is there, the action_reports are there, the views are there.

If I go to the action_reports and use the button "add to print menu" (method: create_action) the reports appear as a print button on my product overviews and they work. So I would suppose this is all fine.

But no matter what I try I cannot add this reports to the "print_format" selection.

This is the code of the python module that I use to activate (and I have already changed  altered it many times without success so there is some unneccessary stuff imported still)


Of course the part "my_module_name" is replaced with my actual module name.

Can anybody help me solve this issue?
