Just happened to notice recently that my HP Z3100 44" printer is not going to sleep. It always did before. I turned it off the other day thinking maybe something would re-set. Turned it back on came back a day later and it was awake.
Anyone else having this problem?
I did upgrade to latest driver and firmware a few weeks ago. Aren't upgrades supposed to make things better!!!

Hello Alan, are you using a Mac or a PC? and are you connected by TCP-IP
If it is a mac maybe this helps
I am using one and just fixed the problem ( I think) It has to do with the connection.
I think I had a connection by Bonjour. It is an easy way to connect , But every now and then the computer checks the connection and -so- the printer is kept awake.
Now i made a manual connection - I gave my printer a number (192.168.2.2) and my second network port of the computer an other number( 192.168.2.1 )
I deleted the old connection in the printer ( system preferences) and established the new manual connection
now Z3100 says zzzz .
