Any idea how to remove this jargon?

Non samba question.

Every time I boot up I get this jargon printed. I thought maybe because the printer was connected to an added slot. I change the printer and monitor this morning and still getting it.

I’m using a maxatec mt-150 printer.

On my old till I never had the problem and it was on windows 7 too.

Its only on boot up, but I printed a gift voucher for a customer on it the other day and its on that.
