ipps cups printer broken recently

[Russell L. Carter]

Greetings,
I don't print much but tax season is coming up and
now I need too.  Last July I had gotten a Brother_HL_L2340D
working via ipps protocol.  Sometime in the last months
that protocol stopped working.  I see that cups has been
updated to 2.3.3op2.  Now it can't see my printer, but a
linux box on the same network sees it just fine:

This is a stable/13 box with up to date ports tree.

$ linux> lpstat -l -e
Brother_HL-L2340D_series permanent 
ipp://localhost/printers/Brother_HL-L2340D_series 
ipp://Brother%20HL-L2340D%20series._ipp._tcp.local/
Brother_HL_L2340D_series_knuth network none 
ipps://Brother%20HL-L2340D%20series%20%40%20knuth._ipps._tcp.local/cups

$ freebsd> lpstat -l -e

That is, no output produced.

When I try to add the printer on FreeBSD using the cups
interface (http://localhost:631/) it can find:

Brother HL-L2340D series (Brother HL-L2340D series)

However the connection is lpd://BRWD80F9967A5AB/BINARY_P1, and
after configuring as a RAW printer as before, it cannot contact
the printer when printing the test page.

I earlier used to kludge this by sharing the printer from linux
cups but now the freebsd box doesn't see that either.  Linux cups
prints a test page just fine over ipps.  Linux cups is version
2.3.3op2, same as freebsd cups.

Anyone have an idea how I might fix this?  Did the cups adjacent
set of packages change so I now missing something essential?

Thanks,
Russell
