Hi, Waterboy.
Thank you for your suggestion. The last link you provided seems to lead to the same page I mentioned at Point 1 in my original post:
- Downloaded this driver for Win 8 (64 bit) http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4132&lc=en&cc=us&dlc=en&sw_lang=&product=5063...
Has it been updated since then?
Best wishes.
