But, they show up even when not connected to the office LAN -- and even with
Networking disabled they still show up.  I'm at home now and they show up.
 Thirty printers listed.  They must be stored some place on this laptop.

Another odd thing is the cups web interface (http://localhost:631/printers/)
the "Delete printer" links have URLs like this:

href="file:///dev/null?op=delete-printer&printer_name=_10_30_1_97"

file:///dev/null isn't going to work.


Geeze, I just tried running strace -e trace=open python
/usr/share/system-config-printer/system-config-printer.py to see what files
were opened (i.e. where the printers might be saved) and found nothing.


Huh, dunno where they keep it either.  Can you delete them with

That worked!  I deleted all that had the file:://dev/null URI shown in the
cups web interface using lpadmin -x.

Now just showing my local printers (as advertised by my local print
spooler).

Been bugging me for a few months now. ;)   Thanks.
