     Following is a suggested rewording of the rewording of the 
     introductory paragraphs of section 3, intended to indicate that a 
     complete MIB II is required for reasons other than the printer MIB. 
     The specific printer MIB requirements for the System group stem from a 
     reference to sysUpTime; the requirements for the Interfaces Group stem 
     from the reference to the Interfaces table. I think this was the gist 
     of the conversation about this at the New Orleans meeting.  By the 
     way, although the question came up as to whether the storage group of 
     the hrMIB should be mandatory, I do not think there was a conclusion.
     
     If there are no serious objections, I suggest this be incorporated in 
     the draft.

        3.  Groups from other MIB Specifications
        
        This section  identifies the groups from other MIB's that shall be 
        supported to supplement and complete a printer MIB implementation. The 
        section also describes some  of the less obvious characteristics of the 
        Printer MIB structure that are related to the inclusion of these other 
        MIB groups. 
     
        Note that, insofar as there is a network node associated with the   
        SNMP agent supporting the printer MIB, network management requires  
        that that SNMP agent implement all of the appropriate groups of 
        MIB-II (RFC1213) for the network node. This requirement is in 
        addition to any explicit requirements of the Printer MIB.
        
        3.1.  System Group
        
        The Printer MIB makes specific reference to certain objects in the 
        system group of MIB-II (RFC 1213). Therefore, an SNMP agent implementing
        the Printer MIB  shall also implement the system group of MIB-II 
        (RFC 1213). However, as described in paragraph 3.4, implementers must 
        carefully consider what constitutes the system.
        
        3.2.  System Controller
        
        The Storage and Device Groups  of the Host Resources MIB (RFC 1514) 
        shall be implemented to support the printer(s) system controller, and 
        any supporting  devices. If deemed appropriate by the implementer, other


        Groups  of the Host Resources MIB (System, Running  Software, Running 
        Software Performance, and Installed Software) may  be implemented.  
        Because of the structure of the Host Resources MIB, the devices 
        constituting the system controller are at the same level as the printer.


        See paragraph 3.4 for an outline of the implications of this.
        
        3.3.  Interface Group
        
        The Printer MIB makes explicit reference to objects in the Interfaces 
        Group of MIB II (RFC1213). Therefore, the appropriate objects in the    
        Interfaces Group of MIB-II shall be implemented for all print         
        information interfaces to the printer, including  non-network 
        interfaces.
