Hi all
I've had the above issue with this printer as soon as we upgraded from WinXP to Win 7 last year.
Have looked extensively on-line and via HP support (HA!) both website and local here in NZ without finding any solution.
The setting changes described don't seem to apply as there is no tick-box for toner saver which I suspect is an old setting from Win XP and now it cannot be changed.
Have uninstalled and re-installed drivers with no result.
If anyone has ideas/solutions/workarounds/etc, I'm open to all.
Many thanks
TM
