Try and select "Print" from the menu instead of Ctrl+P. Instead of bringing up the system print dialog, this brings up an interface where you can tweak the print layout. No idea why it isn't the default view when pressing ctrl+p. At least there I feel it's basically the same as Chrome when printing.
On my Linux system Ctrl+p and File->print are the same dialog box.
Mozilla is fixing a lot of Firefox printing issues for Firefox 81 (September 22 release date).
