Label printing in stock entry form

There aree a few posts regarding how to print labels in ERPNext. But there is one that says that a print format was introduced in V12 with a checkbox “Print Labels” in the Stock Entry Form Table. for printing 1.5" X 1" labels.

In V13 the check box is not there. If the script is in the files how do I enable it in the form to print them ?

Thanks
