+===== Reset HP OfficeJet Pro 8600 Plus =====
+<code>
+My printer is a N911n, and I have not found a consistent way to reset it.
+I did get the Home, Back, Home, Home to work possibly one time a couple months ago, so not sure if the Oct 31st firmware changed something,
+as I have not been able to do any kind of reset.
+(tried the Back x 4-5 times as well at boot up, but nothing happens, after power off/unplugging for 1-10 mins).
