Are you running this under Ubuntu?  Is cups-browsed installed and running?  
Are the ricoh printers network printers? If yes to all of that, what is 
probably happening is that cups-browsed is using Avahi (Bonjour) to "helfully" 
configure your printers for you.

I *always* uninstall cups-browsed. It is a pain in the ass and causes far more
problems in an organized managed LAN. I guess it is fine for someone who is
generally clueless and/or who "wanders" from LAN to LAN (eg a traveling
laptop), but for a situation where there is a sys admin who has configured the
printers just so (for whatever reason) an who does not what the reconfigured
as per someone else's ideas, who might be trying to be helpful for a clueless
end-user.
