So I reset the printer's wireless settings back to default and reconnected it to the MR33.
Here's the message I'm getting:
"Print communication problems detected. You may experience limited functionality when printing to your printer from your PC.
If you are using firewall software, verify TCP port 9100 is unblocked from your PC to your printer at 192.168.x.xx.
To fix the issue(s) try to power your printer off and on.
