consideration of Ira's recent eman communication. (copied below)

Thanks,

Hi Daniel,

Relevant to your questions, you might want to look at our IEEE-ISTO 
Printer Working Group candidate standards for Printers and MFDs:

"Power Management Model for Imaging Systems v1.0"
ftp://ftp.pwg.org/pub/pwg/candidates/cs-wimspower10-20110214-5106.4.pdf

"PWG Imaging System Power MIB v1.0"
ftp://ftp.pwg.org/pub/pwg/candidates/cs-wimspowermib10-20110214-5106.5.pdf

"PWG-IMAGING-SYSTEM-POWER-MIB" - ASN.1 source
ftp://ftp.pwg.org/pub/pwg/candidates/cs-wimspowermib10-20110214-5106.5.mib

The PowerLog group defines a FIFO list of state transitions
with time stamps.

The PowerTrap group defines a notification to report state
transitions.

The PowerSupport group defines objects about the capabilities
of the device (or component/subunit) in a given state.

The PowerTransition group defines objects for nominal state
transition times between any two supported power states.

The Power[Calendar/Timeout/Event] groups define objects for
configured power transitions for device or component based
on calendar (like IETF Schedule MIB), timeout, or event
triggers.

BTW - This MIB uses the standard DMTF CIM power states,
but allows vendor extension substates (e.g., fine-grained
Suspend substates).

And this MIB defines explicit light sleep (Standby) and deep
sleep (Suspend) states and their standard behaviors - note that
Bruce Nordman does not like the use of these terms, but all
Printers/MFDs that support power management have always
made this distinction in the their private MIBs and embedded
web servers.

Cheers,
- Ira (editor of the PWG power standards)
