When I open "printable version" on any page, Wikipedia will automatically open the print dialog.
I have confirmed this behaviour with Firefox, Brave and Safari (all on Mac), in the English and the German edition.
This is not the expected behaviour and not how it has been previously. (Although I cannot tell, when the regression occurred.)
It used to be and should be, that "printable version" or "Druckversion" opens a, well, printable version. Nothing more.
It is then up to the user to actually print. But maybe the user wants to copy text or it is the user's preferred reading layout.
Please amend "printable version" and restore the previous behaviour. Thank you.
