"hplip" and "hplip-doc" were installed; "hplip-gui" was not.
After installing "hplip-gui", "hp-toolbox" still failed to find the installed printer, but was more informative. It invited me to use either CUPS or its supplied "setup" routine to install the printer.
When I selected the "CUPS" option, CUPS confirmed that my printer (HP Deskjet D1360) was installed; when I selected the "hp-toolbox setup routine", the install failed; the setup routine was unable to find the required "ppd file".
Going one step further, it seems most probable that the (supposedly) missing "ppd file" is present and called:
However, since the printer (and the CUPS install) work perfectly, I am reluctant to press the required button demanded by the "hp-toolbox setup" without checking back.
It does look as though the diagnosis that this is an "hp bug" and not a "Debian bug" is correct.
Meanwhile, I would like to post my thanks to all who responded to my initial query.
