I deleted that configuration and tried again using the CUPS web interface. This shows up as:

I suspect this detection doesn't adequately check the details of the IPP support. Given the age of the printer, IPP may not be implemented "properly" by current standards.
Printing a test page again shows "Unable to locate printer". This happens both using the generic IPP driver and the specific model driver from the RPM package.
I looked at the Brother DCP-7055W Advanced User's Guide, which is dated 2012. I can't see any mention of IPP or AirPrint.
The User's Guide and Networking Guide are both pretty basic and mostly talk about using the manufacturer's admin utility for setup under Windows. However I was motivated to try the RPM package because it explicitly lists the DCP-7055W as one of the supported models.
