Guessing you are over 80. Beg a friend or relative to borrow their gear, hotel business lounge , or at an internet shop or printing store?
Print shop again? Emailing to hotel front desk staff usually happy to print something simple like this. My experience with Singapore is Border Force scan your passport and everything normal, no need to show or reference the code.
Maybe they did not think this TDAC as well as they could have, or what is the definition of resident?
180 days? Work permit? One year extension?
More and more countries rolling out these kinds of required processes get used to it or don't travel internationally my advice.
