Is EcoMode enabled on HP MFPs via SNMP?

Question

SNMP

The essence of the problem is as follows:
There is an HP LaserJet 400 colorMFP M475dn MFP, in which, according to the documents, the eco-mode is not present, it is not in the MFP settings and is not in the web interface. BUT if you look at SNMP, then OID .1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.6.7.0 (responsible for the eco-mode in HP MFPs such as the HP LaserJet 400 MFP M425dn and in the HP LaserJet 400 M401dn printer) is present and can be set to enable or disable eco printing.
Attention to the question:
Does the eco-print actually turn on or not, or does this OID go to the void?
PS There is no way to visually check the print quality. HP support engineers, I don’t understand what I want from them at all))))

Answer 1

Empirically found out - the eco mode is ON !!!
And it is used only for copying, when printing from a computer, the eco-mode must be set in the drivers.
