[cups] programmatically detect network printer power state

[Boncek, John]

With CUPS 1.7.2 under Ubuntu 14.04, I am able to programmatically add a network printer (an HP Officejet Pro 6230) at a socket IP address and port combination, make it the default printer, and send jobs to it.  Now I want to programmatically detect whether the printer is on or off, but I haven't been able to find a way to do that.  Regardless of whether the printer is on or off, CUPS seems to always report that the printer is Idle, Accepting Jobs, etc.  How can I detect the power state (if there is a way)?

By the way, my messages to the list seem to unwrap into one very long line (I've seen some messages by other people that are also like that) - is that a limitation of the list or is there something I can do better?  I use Microsoft Office Outlook 2007.
