Defining the visibility of elements
A JSON condition can be used to define (independently of the PFNonPrint layer) for individual elements (blocks) in which media (editor, preview PDF, print PDF) they should be available.
To do this, the following condition is set as an attribute on the block:

{
"left": "${pf-meta-display}",
"operator": "equal",
"right": "editor"
}
With the “not-equal” operator, the element is not displayed in the editor, but is displayed in the preview and print PDF.
The following image shows all options including the respective condition:
