Cleaned PDFs wont print correctly (on some printers at least)

Hey,

I generated a PDF from a LibreOffice document, passed it to mat2 and tried to print it on a Xerox 7545, by pluging my USB stick directly into the printer. It did something quite weird: the printed doc was only the bottom left quarter of the original document, zoomed to fit the entire A4. We tried with other documents, PDFs generated by other programs, but same happened. We also tried a A3 document, same happened.

Printing the same documents but before it goes through mat2 works fine.

I didn't have the chance to test it on other printers yet though, so it might come from the printer.

(i'm not sure if creating an issue for this is fine, but i didn't know how to raise the problem otherwise)

thank you for the hard work!
