Hi, just mentioning that I'm still looking for these drivers if anyone has any to share please!
Also I'm updating my request to include *any* Z3200 model, plus the Z3100, plus any version of Windows. (And I'm tempted to open it up to any Z-series printer... Z2100, Z5400, Z6200...)
This is safer because some driver download files are for a specific printer/OS combination, while others include many. So even if you have a completely different printer model, you could still have a driver download file that could help me.
I did find an installation CD here buried among some ink cartridges from the previous owner, so using that helped fix some issues. (The CD installs an HP "print monitor", which I think is a key part in the bidirectional comms needed for HP Utility, Colour Centre, etc. to work correctly.) It had a 2010 driver (61.101.362.21).
I then found some older drivers using the Windows Update Catalogue, but it doesn't have all of HP's driver versions. In addition to 2010 and 2011 versions, the "newest" I could find that mostly works so far is from 2012 (61.121.362.41). Then there is a huge gap to one in 2018 (61.183.21507.100), but that one doesn't behave well. After that is only 2020 and later, which are the much-detested "V4 / universal" drivers.
I've seen several other driver versions mentioned here on LuLa, so I know there are more out there...
Thanks!
