May I be the first to say if you share a lexmark printer you will sonner run out of ink and that means you will have to buy either new ink (which is incredibly expensive for lexmark) or a new printer (which would be my choice and it would not be lexmark)
I hope your Dad realises what he has done and gives you a swift kick for not learning anything while you have been here and allowed him to make the stupid mistake which is buying lexmark
Its only 2 days old you still have time to say it doesnt work and take it back
