I have an HP Officejet Pro 8500A Plus e-All-in-One Printer - A910g and have been printing quite happily to it from my Android phone using the HP ePrint app. Recently it has stopped working and I have a red dot as the status on the left instead of the usual green one. I have checked that I am running the latest version of the app and that the firmware on the printer is also at the latest version. I have the same problem from my other two Android devices (another phone and a tablet). I have tried rebooting the printer and resetting and removing and installing the app, but there is no change. I can print to the printer from my desktop and laptop without problems though.
What does the red dot indicate? I haven't managed to find any information or help on the app so that I can diagnose the problem.
