Looking for HP DesignJet Z6200 Photo Production Printer drivers

I discovered no macOS drives available for that printer direct from HP, however, I did find this:

As @MrHoffman has noted, it does appear to be a rather old printer, so connecting it to the modern Mac may be difficult at best.

I’d start with asking HP Support, and with the Apple App Store and the HP app, though this appears to be a very old HP printer (2010?), and specialized, with only Windows and Linux support shown, and with no AirPrint listed, and seemingly also without IPP/IPPS support.

You might find a compatible JetDirect card with AirPrint support or with IPP/IPPS support, which would be one path.

Also poke around at the https://hp.com/go/designjetupd website.

The other is to feed it from Linux or Windows.
