I keep three browsers active: Firefox, Chrome, and Opera, all on Windows 10 64 bit.
Of these, the one that works consistently well with LuLa is Opera (version 68, April 2020.)
Firefox has not been able to print correctly for a few years. I am on the latest version (77.0.1 64-bit), but still if I try to print a single page, it empties my printer of paper without printing the page I want.
