I had some input on similar thread before Christmas. I bought a new z3200, and installed the HP printer utility on the first machine on my network using the version of the utility as it existed on November 8th. Works flawlessly great on my Windows 10 x64 machine.
A few days later, I began to install the utility on my second machine, and noticed that HP had "updated" the z3200 utility on November 09th. So, I downloaded and installed that version.
In short, total disaster - the updated utility was mostly non-functional. So, I simply uninstalled the post November 9th utility and installed the previous version (which I had, fortunately, saved), and the second machine returned the same result as the first - it works flawlessly.
I emailed Mark a few tomes back and forth about this issue, and he asked me to send the utility to him to put on his website. Unfortunately, after several attempts to get it to him, it appears that his email server blocks any file I send there with an attachment as a safety feature (at least according to my reply-path messages - regular emails without attachments get through just fine)
So, I'm not sure how to get the functional version of the utility back out there. (I don't have drop box access on the network here)
