Hallo Kurt and all, sending SIGHUP to *all* smbd processses works.
(using samba 2.2.6)
bye,
Martin


Thank you Martin,

The "*all*" is probably the key to *one* (small) part of the problem.
(However, I can't test and verify this at the present time).

But the main part of the problem still remains: The Windows
clients don't get the updated printer list automatically, not even
after a long time of waiting. They can't send a SIGHUP to all
smbd processes.

Using "Update View" ("Ansicht aktualisieren") from the client *does*
spawn a lot of activity in the log.smbd; the "Printer Folder" window
(the one where you access the Samba host via Network Neighbourhood)
goes blank and rebuilds after a few seconds  --  but still shows the
"old" list....

So, as a Samba admin, do I have to remember to send SIGHUP manually
to all smbd processes, after every single deletion or addition a
(CUPS) printer, to make sure my users have an uptodate view? Is this
by design? Or is it a shortcoming? Or a bug?

Cheers,
Kurt
