When opening one order, down at the footer menu you will find the 'Print' option, which is also available in other parts of the application. 

It allows users to configure and initiate print jobs and provides various settings and options to customize the printing process according to the user's preferences. You can generate PDFs, send emails, generate printing jobs of the order or send directly print jobs to the Print Server

The request codes are applied in the layouts, as in default neoCatalog layouts.
