I’m having a strange issue when printing from LibreOffice. It always prints with rectangles under some letters which looks like this:
When I try to print out the test page for example there is no issue and neither when I print the very same document from another computer using Word. That’s how I know the printer is working fine.
I tried changing default printer language type to postscript but it didn’t help.
Build ID: 1:6.0.7-0ubuntu0.18.04.2
Do you have any idea what might be causing the issue?
