I've noticed that macOS appears to default to using secure AirPrint as it's printer driver over the manufacture's printer driver. Any reason why I should choose one over the other?
In the near future, there will be a macOS update. Your printer manufacturer may or may not release a timely driver update that matches the updated OS. As a result, your system may become unstable, not be able to print or worse.
My strong suggestion is that, unless there's some mission-critical functionality you need, it's always best to go with the built-in drivers. With it, there's a much higher probability that your system will remain stable through multiple OS updates.
