Issue 1: Engine Communication Error A couple of months ago, the printers started reporting "Engine communication error". Our initial thought was to remove all unused IPv6 features [SLP, DHCPv6, LLMR] and re-add them one by one to determine the cause. When we removed all three, the problem went away. But, after re-adding all three, the problem still has not re-occurred. Has anyone else had seen "engine communication errors"? It is hard to tell the faculty that the problem is "fixed," when we do not know what caused it in the first place. As HP believes this is a "network issue," they will not provide any assistance. Issue 2: No AirPrint Printers Found On iPads and Mac laptops, we can always see and print to the HP LaserJet 100 printers. However from iPhones, the printers often cannot be found. Sometimes, we can see one of the printers but not the other even though they are connected to the same SSID and on the same AP. We have tested with both iOS 6.1.2 and 6.1.3 (the same versions on the iPads). To isolate a bluetooth or carrier conflict, we have also tested in Airplane mode and have gotten the same results.
