That is an anonymous bind,  which is reasonable unless the printer also 
supports Kerberos (doubtful).

Right,  but you've probably got a default search base which the printer 
isn't specifying.  Are you sure you can't telnet/http to the printer and 
set a search base?  Does it enquire of your DNS server for SRV records?

Otherwise set defaultsearchbase in your slapd.conf to the base you want 
the printer to search from.
