Re: Page count and serial number attributes?

Thank you for the reply.

Our thinking has been that IPP returns so many usable attributes that it 
closely approximates the value we would get from using

SNMP, without having to deal with vendor-specific MIBs. One of the last 
areas we would probably need would be page count(s).

Is there any documentation on which print vendor(s) implement the RFCs 
most completely?
