This can be gotten to work for 1.4.6 by KLUDGING THE DEVICEURI:

> <Printer brothermfc8420>
> Info Brother MFC-8420 BR-Script3
> MakeModel Brother MFC-8420 BR-Script3
> # DeviceURI usb://Brother/MFC-8420
DeviceURI parallel:/dev/usb/lp0
> State Idle
> StateTime 1286042213
> Type 8392772
> Filter application/vnd.cups-raw 0 -
> Filter application/vnd.cups-command 0 commandtops
> Filter application/vnd.cups-postscript 0 -
> Accepting Yes
> Shared Yes
> JobSheets none none
> QuotaPeriod 0
> PageLimit 0
> KLimit 0
> OpPolicy default
> ErrorPolicy stop-printer
> </Printer>

So I repeat my question, with a slight clarification:

   What can I *properly* do to configure my printer?
