printers listed after deletion

[antonio montagnani]

I deleted a network printer and then I reinstalled (by Hplip, by cups, 
by system-config-printer, for testing) and while in Hplip, Cups or 
system-config-printer I get only one printer in the list, if I print 
from Firefox, Thunderbird for example I have in the list also the 
deleted printers that were installed with different names. Why?

They might be caching printers, there was another post about the same
kind of thing in the last few days.  They went away after a while.

There could, also, be a mix of user-configured printers and
automatically discovered ones.

That would be me.  "Most" (watch the weasel word) of
my programs found the deletions.  Some held on
to them.  Never figured out how to get those
few to finally update.

Hold outs:
    Wine (all of them)
    Libre Office
    Free Office
    Master PDF Editor

The previous thread has been "aged out" of my folders.  So, this question may
have
already been asked.

Have you tried those holdouts with a different user to see if it a "system" or
"user" issue?

Never mind.  I found a system here with that issue.  And it isn't a "user"
issue.

Humm.....

Ahh, never mind again.

libreoffice was sending out mdns requests and someone setup a printer on the LAN and
reused a name
they shouldn't have.

even if LO is sending mdns request, the discovered printers should be shown
also in cups or in system-config-printer. Am I wrong??

They are not being shown in either cups or system-config-printer.

This is the case even though View-->Discovered Printers is checked in
system-config-printer.

I did find why that was not the case.

After an update to cups a cups-browsed.conf.rpmnew was created. However, it seems I
failed
to check that file and make it the default.

system-config-printer and cups (localhost:631) now do show that printer.
