SNMP storm between my laptop and HP4500

[TheGear]

For some time now, my printer has been very slow, printing for half a second and pausing a second (more or less).  I finally put Wireshark on the network and verified that the packets to the printer have the same timing, so it's apparently not some sort of queueing problem in the printer.  However, I also noticed that there is a huge amount of SNMP traffic between my laptop and the printer.  I presume that this could be related to the delays I'm seeing.  Problem is, I can't find what's causing the SNMP packets. I've killed every HP-labeled process on the laptop but the SNMP traffic is undiminished.  Any thoughts on what to look for?  I saw one article that said that printer sharing can cause this, but this printer is not shared -- it stands alone on my LAN.
