I assume this was meant for me rather than the list.  Bill and I are both
at Clemson, and gutenberg, guthrie, and ramanujan are IP names of HP
network printers in our department.

I *think* we are talking about print servers or locally attached printers.
Browsed printers don't seem to end up in /etc/cups/cupsd.conf.

There are loads of garbage printers (presumably badly configured printers
attached to student, faculty, staff, or office machines) that show up on
our network when browsing is on.  The HP network printers accept IPP but
don't broadcast, so I have them configured by hand as CUPS printers.
They are also accessible through JetDirect or a Solaris LPD server. I
could get away without browsing at work.

At home, my print server does broadcast, so I do use browsing.  (I could
do it without broadcasting, but it works so nicely with it, mostly.)  But
my USB printer shows up twice in cupsd.conf on my server, once as CUPS
detects it and once as the USB subsystem detects it.  Those lines appear
below a line that says
