The "Status" value tells you some of that information.  The bits are
defined here:

Power state is a tricky thing for the system to handle.  The spooler
wants to allow you to submit print jobs even if the printer is off or
offline, because it will probably come back at some point.  I suspect
you will find PRINTER_STATUS_SERVER_OFFLINE in that case.
