receipts.cafe - Send An Anonymous Message Directly To My Receipt Printer

I made a simple site where anonymous messages are sent and then physically printed as thermal receipts at my house. It is called receipts.cafe: https://receipts.cafe A few guardrails are built in so it does not become a printer-destruction machine: 300 characters per message, 3 messages per hour per person, duplicate suppression, and basic spam filtering. Everything is being archived and I plan to put up the archive for viewing after i get 1k messages. I'm planning to have the archive
