From my perspective it is incorrect to say 'impossible to close "Print Preview" window' I can run kate in miral-shell, open the print-preview and close it (Alt-F4) fine.
Now I do agree it seems daft that there's neither a "Close" button (or equivalent) on the window, nor an "X" in the titlebar, but isn't that down to a design issue?
