In print preview it looks fine, and yeah that's A4, the paper under it with the words test in the corners I printed from Libre Office where I set the margins to minimum and put the word in each corner and it printed fine.
I did not think of exporting to PDF first though. I did that which worked fine, then printed the PDF and it came out fine. Only thing I find weird, and this is probably a Linux issue, but it only prints one page at a time. Printer spools up, one page comes out, spools down, then spools up etc. I don't do a lot of printing thankfully, otherwise it could take ages to print anything with like 10 pages.
