All well except I lost ability to Scan from my HP printer

I have just installed El Capitan and all seemed to be going very well until I tested my scanner (HP LaserJet Pro color MFP). The printer seems OK but I can no longer scan to my computer. So far I have tried deleting and reinstalling the printer, cycling power to both my Mac and Printer, installing the latest version of HP Easy Scan and no luck so far. Disappointing since this is a function I use very often.

Other than this issue I have to say that my old Late 2009 iMac seems to have received a nice performance boost with this latest OS version
