When trying to print from a website, i always get the 'Load Legal' message on my old LJ HP4+ printer.
Hello, I'm using Kubuntu 21.10 (language German) The printer is a very old HP Laserjet 4 Plus with a network card 10Mbit Network card. the IP adress is 19x.xxx.xxx.5. When printing from any other app/program is working fine Firefox on Win10 is no problem and with all other programs running with WIN10 or Linux, like Libreoffice, Kate, Okular etc., there is no problem, just with Firefox. The paper is set to A4. Not to US-Legal or Letter Maybe i screwed something in the settings, but i don't think so.
