I run windows 8.1 Pro using VMWare on a Mac Tower.
Unfortunately, the Mac version of HP Utility has been degraded as they have released new versions of Utility.
There is no longer a GUI for paper preset management, just some arrows and dropdowns. Big disappointment.
Now I prefer running my Zseries printers in Windows, and thanks to Ernst and Hugo and others, I do print largely with Qimage Ultimate. It's very easy to drag and drop image files from the Mac into a folder on the virtual Windows machine, then print either with Qimage or CC products.
I prefer using this method to getting a separate machine to be usede as a server, since file sharing is seamless via VMWare, which works flawlessly.
There is no question, however, Windows is the way to go now. 8.1 Pro is great. I have found the drivers and utility quite stable. It's nice to have so many printing choices, as sometimes I still use photoshop or lightroom directly on the Mac.
Easy Peasey. Finish your image on the Mac. Drop it into a folder on your Windows machine running on your Mac, then print with your choice of programs.
Piece of Cake once you get used to it. VMWare is pretty reasonable, Photoshop CC and Lightroom can be installed on that Windows machine for free, if you already have it on your Mac, and Qimage Ultimate is like $100.00.
Way cheaper than a crappy windows computer, and works seamlessly with VMWare.
Badda bing! Best of both worlds.
