Poco Printing FAQ - Adding a "Print Preview" button to the toolbar

Q: Is it possible to add a print preview button to the Poco toolbar?
A: You can configure one of the custom buttons for the print preview function. To do this open the scripts form by pressing F9, press the "Buttons" tab and for one of the unassigned buttons enter /menu/print. Enter a description beside it and close the form.
One additional step may be required for Poco 3, configuring the toolbar to either display this user action button or the PocoScripts Section.
