I'm curious what printer you run that uses a lot of standby power. I have checked several with a kill-a-watt and none of them seem to use more than a watt in standby mode.
It's actually 3 devices behind one plug - Xerox Phaser 6600 printer, Brother MFC 7840 multifunctional and a ScanSnap ix500 scanner. I don't quite remember, I think they used 20w in standby (combined)? I remember being shocked at the time, but I don't think I really dug any deeper.
