Hi @Hellis81,
This is a relatively old Lexmark B/W printer. Its a E120n printer and one of my favorites. What you see in my initial post I been working and re-working. Hardly finished. I been checking over at Free LEXMARK-PVT-MIB SNMP MIB Download - Free MIB Download - Search MIBs - OiDViEW. I found more confused from the values returned by Paessler SNMP Tester. I am trying this code to follow the one posted over at HP Printer over SNMP - #15 by vingerha. For whatever reason cannot delete that thread. Rather keep things over in this thread. I had also posted over there, but no one offered to help.
Whatever help you can offer much appreciated.
