Thing offline Content is not allowed in prolog


I’m trying to a HP Mfp but both the autodiscovery as manually adding by id show the Thing as offline with Content is not allowed in prolog. as the error. Anything that needs to be set at the printer ?


Read the “How to ask a good question” thread first.


Seems my printer does not have a /DevMgmt/ProductUsageDyn.xml page, so I assume the binding will not work. I will switch to SNMP instead I think
