Phone software, printer software and HP Smart app are all up to date
HP Print Service Plugin is running on the phone
Laptop: Windows 10 (FYI) - no trouble printing or scanning from laptop
I can print from my phone using HP Smart app with no difficulty. I cannot scan. I press the "Scan" button in the app, the printer itself starts to scan, and less than 5 seconds later the app says, "Scan Error - Scan unsuccessful". The printer then says, "Scan cancelled". Scanning from the app on the phone used to work. I uninstalled the HP Smart app from my phone and re-installed already - no change.
