I suspect what you say is true since network printers would be picked up
through cups browsing from the printer server.

The solution is really to delete /var/cache/cups/remote.cache
but the cups process has to be stopped, first. Otherwise,
the same cache is recreated if cups is just restarted.
This cache contains all of the network printers.

Therefore, the solution is:
1) stop cups
2) delete cache
3) start cups

Finally, I got rid of all these ghost printers...
