I am not familiar with the different firmware, but I have not updated mine z3200Photo(not PS), as in general computer and electronics...If it aint broke dont fix it, does apply.
The HP Click software works on Win 10, but the HP Utility does not. HP Click give me accounting and all sorts of status and monitoring, but the printing interface is pretty useless as I use Q Image. But I am needing the Utility and is not working. Not sure of the issue, but it keeps looping a bootup of the app and cycles loading. I cancel and it does not so I kill it in Task Manager.
I just purchased a used z3200 Post Script model, as Mark who helped me work on my printer when it had issues, recommeded I get one of those. I did, and I will want to basically move the PS parts to the z3200Photo, as it is not heavily used. The PostScript I purchased is not so much a PS/piece of s***, but it is much more used, as a error 56 code, and recently got a new service station. So I may move that to mine or get a new one, but will swap formatter board and HDD for the PS upgrade. I think that is it?
Either way, ya, I would not upgrade unless you need. I think I did a upgrade one time as there was some cutter issue that would hang.
