Ok, done!
root at marquez:~# /usr/sbin/cupsctl --debug-logging
root at marquez:~#

The id was HP_Color_LaserJet_Pro_M252dw_501595_-13 so presumably "13"
was the number

Here are all error_log entries starting with 13/ :

Ahh, so that's the wrong driver to use.  I was kind of hoping this meant
it would got PS all the way.

What's the best driver to use for a dual side printing color native
PostScript printer?

Thanks for looking into this! :-)
