As I have explained on other threads, my advice to Vista, and to a lesser extent, XP users, is to leave well enough alone.
If your system works, don't mess around with the new firmware or software.
There have been a large number of serious and crippling problems for the Z3100 with Vista. It works OK with some systems, but not with others.
HP in Spain actually REPRODUCED these problems but never solved them. At least not to my knowledge. Talk about irresponsible tech support.
At the moment my system works OK and I can print. (I am forced to print directly and not use the spooler, however.) That is all I want. Forget about the new features. If your system works, and if you are using Vista or XP, my advice is to be happy and let well enough alone.
Ignore the siren's call and lure of the new firmware.
(With reference to reds, does anyone know if the new firmware even addresses that? I think that was covered in previous firmware releases.)
