I use Libre mostly for copying pictures from the internet and printing them. It works well for that. I am not a very sophisticated user. But, I cannot type a letter in Libre and get it to print. The printer puts the paper through, but it comes out blank.
For a Writer file with text in it.
What does the Print Preview of Writer show you?
What does the pdf-export of Writer show you?
Same here. Cannot get a letter to print from LibreOffice but my printer works for other uses. I downloaded latest version of Libre and that did not fix the problem. This is happening with people with all different kinds of printers. The file shows up in the Print Preview though.
