Printing text from Catalyst Mac app

In the chapter 11 description for Barista Training: Toolbar

In this chapter, you’ll learn to customize the toolbar items, including Share, Insert and Print.

I can find no mention of Printing in the entire book.

Is there an update or another tutorial that shows how to print from a Mac Catalyst app?

UIPrintInteractionController is the central class for printing in iOS. The shared instance of it represents a print job. A print job includes the content to be printed and information and options related to its printing, such as output type, job name, paper size, and orientation.
