if you are talking about non schengen lounge , before covid i had occasion to request a photocopy there , but cant recall if they had a printer ... i asked a lady at reception and she brought me the document to my table at the blue bar

but i guess with covid there are less agents , and therefore less devices .... your 2nd option might be the lounge 26 in schengen area , if you have access and if its open before your flight

Anyway , regardless if they have printers or not , i would suggest to never rely on lounges for such important matter and find a way to do your work before flight , cause you are just gambling, so consider the lounge as a nice help in case you are in light troubles
