No errors on the printer, and now I find that in addition to the test
pages mentioned, it prints a .ps saved to file from libreoffice
immediately, without any problems. But postscript output by xpdf, which
is what I had to hand for the post-installation tests, is still queued
and lost without output or visible symptom. So, to probe what's up
there, I printed to file from xpdf, then lpr-ed that, as I had done with
the saved .ps from libreoffice. That disappeared too, so it seems that
the ps from xpdf is somehow unprintable, though they're all %!PS-Adobe-3.0. 

For the moment, I'll put it down to an xpdf problem, rather than cups,
as another .ps I had to hand prints too. Ah ... printing directly from
libreoffice, something I very rarely use, works too. It's mysterious
rather than a show-stopper now, so we'll see how much effort I put in
later to try to print from xpdf and anything else which fails similarly.

Thanks for the inquiring mind.
