BTC Hardwallet Address Keeps Refreshing

Question for the community here: I’ve had experiences in the past where I’ve sent exchange-purchased BTC to a hardwallet. However, in each instance of receiving the BTC, the hardwallet’s recipient key changed. I like this is a security feature in general, but am wondering how/why this occurs and if there’s a way I can make it not occur. Basically I’m gonna be launching a project and want to receive only BTC for payment, and wanted to print out a QR code for people interested to scan, which would take them to the wallet I set up for the project. If the address of said wallet changes perpetually, though, I don’t see how this can work. Am I missing something here? Any advice would be greatly appreciated.
