- Did you download the Windows 10 drivers from the HP site? http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=nl&lc=nl&dlc=nl&product=374568 shows there are drivers both for 32 and 64 versions of Windows 10.
- What happens if you install them according to the instructions?
HP printer software is rather big and rather complex to install once in a while. Then you might need help from their customer service.

I seem to be unable to get my HP1315 to scan and print since I have downloaded Win10. The pc just does not recognise the drivers? Any tips or others having the same problem?
