Football Match

I am tourist on Malta and I bought 2 tickets for match Malta-Bośnia (which is Tomorrow). I have 2 copies of e-tickets but there is an information that I need to print ticket. I think I wont be able to print it before the match, is it really necessary? That e-ticket has qr code etc so its weird to me that I need to print it. Can someone tell me do I really need to find some place to print it?
