With the Designer, you create or edit different print templates for printing information that originates either from a database or another data source. In the Designer, you then have all the data at your disposal and can prepare it for printing in different ways.
The Designer always uses the data that is passed from the program, in other words, the application handles the process of selecting and compiling the data.
Thus, "the Designer" is not a self-contained application, but rather is incorporated in an inherent part of an application.
The Designer the print, preview and export dialog is normally started via a menu item (e.g. Configuration > Print or Output > Print).
