@pint6,
Welcome to HP Forums, this is a great place to get support, find answers and tips.
Thank you for posting your query, I'll be more than glad to help you.
I understand that you wanted the drivers for your HP LaserJet Pro MFP M126nw to work with Win 2012 server.
You may download the drivers from the link: PCLm Driver Only (no Installer)
Let me know how this works.
You have a good day ahead.
