Can't view Django's print statements with `journalctl -f -u daphne`

I’m moving my Django application from an Ubuntu server to a Debian one.
On my Ubuntu server, I am able to see print statements from my Django application with journalctl -f -u daphne.
On my Debian server, I’m not seeing print statements with journalctl -f -u daphne. I see other messages like when a request is refused.
I’ve combed through all the configuration files I’m aware of on both servers, but can’t find anything that appears to affect this.
Does anyone know how to configure Daphne, Django, or systemd to show Django’s print statements with journalctl -f -u daphne?
