Printing A1 posters in building 100

Hey folks 🫩 It’s that time of year. Hope you’re all keeping well as can be. So I had a mini heart attack looking at the cost of one A1 poster at Officeworks - $25.5 and my group needs two.

I’m not a design student. Can someone confirm that I’ll be able to use the printers in building 100 to print an A1 for around 5 dollar printing credit? As long as I have my login/ID card.

Thanks in advance!
