Hi Bestof2Both,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I see that you are looking for drivers and software for your Windows 8.1 RT operating system. I have found a document that explains how to Install the Printer Software in Windows 8 on a Tablet.
Please feel free to write me back if you have any other questions.
Thank you for your time.
