Black line/letters on top of the paper when printing from Writer

Hello,

I’ve recently moved from MS Office to LibreOffice and i’m enjoying it, but there’s a problem.
Anytime I try to print anything, a line with black letters appear on top of the paper, the line doesn’t show in the screen nor on the print preview, I can also print the same text from microsoft word online (the one you use on your onedrive account) and it works fine, so it’s not something about the printer, it’s about Libre Writer.

I’m using LibreOffice 5.0.2.2 x64 with both english and pt-br languages installed on Windows 10 x64.

I’ve taken a screenshot of my text (just a little warning to visitors to my building) and a scan of the same text, but on paper with the black lines:

As you can see on this link, nothing shows on top of the document on writer or the print preview, but that weird row of letters appear on the printed paper.
Just now after this happened I tested on word online and I was able to print without any issue.

Any idea of what could be causing this?

Thanks in advance,
Felipe.
