My humble personal feeling is that networked printers should be on 
RFC1918 private IP addresses.

In almost all cases there is neither a need for them to be accessed from 
the Internet (e.g.
people printing from the Internet to your printers) nor a need for the 
printer to access the
Internet.  The printers just end up getting attacked from the Internet IMHO.

Moving a few thousand networked printers to 172.16.*.* is one of my 
initiatives for this next year.
