All that comes up is the print preview screen when trying to print a document with Libre Office 6.4 on Linux Mint Cinnamon 2010, but this has only just happened as up to a week ago printing was fine. Not I cannot print anything.
Cannot print anything even though printer is set up correctly I have a linux Mint Cinnamon 20.10 o.s
Please check the OS logs. Does printing form other applications work as expected? Can you print from LO to pdf using system pdf converter?
