Printing issue (only in LibreOffice)


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.

I’m using:
Build ID: 1:6.0.7-0ubuntu0.18.04.2

Do you have any idea what might be causing the issue?


How it looks exporting in pdf?

And how does it look in Print Preview?

In both cases - it looks like it should, no issues!
