Try doing an SNMP table-walk. I didn't get to test it completely before my
most recent contract ended but this is what I found:

I had been testing BESTview, an SNMP network monitoring tool that uses SNMP
Research's code (including 'getmany' et all). When our product did a
"full re-detail" of our HP 5MXsi, the printer would crash, displaying
"Service Error 80" on the printer display. I assume that our product was
doing an SNMP table-walk but didn't have time to research it thoroughly.
