My HP ENVY photo printer/scanner 6255 works fine by itself and the scanner works with the Windows 10 PC. I have tired downloading drivers and running the HP Scan and Print Doctor 5.0.7 but nothing works. Device manager has the scanner icon (I think..looks like the printer icon) but when running the scan doctor it stops when I try to make the printer the default printer. I suspect windows 10, not the printer but have tried everything I can find on the internet and HP support sites and I know just enough to be dangerous. Any suggestions?
Suggest checking the IP addresses of the printer and PC and router. The setup instructions for the printer likely describe how to find what the IP address is, and should also describe how to set the DHCP to "automatic". It may be that the printer settings change it's IP address whenever it's turned on; that address change is likely why Windows 10 sees the printer as "offline".
