Hello,
I have the exact same problem. When I first set up my HP Photosmart e-all-in-one B110 on my wireless router, it worked just fine as an Air Print printer from my Mac, iPhone4, my wife's iPhone5, and our iPad2.
Then the first problem after a few months was the B110 would sometimes show up as an AirPrint printer, and sometimes it would not. Showing a message in iPad of "no AirPrint printers found". But the printer is veritably there, and the WiFi connection still the same.
And finally now, the B110 never shows up on apple devices. We always get the "no AirPrint prnters found". This means we are now totally unable to print. The B110 does not connect using USB, so in fact AirPrint is the only way, as we are Apple environment users.
I have done all the suggested fixes. Download latest firmware from the Printer's control panel. Shutdown, power cable out, leave, restart, re connect to the WiFi router, run the WiFi connectivity test - which comes out fine with a proper IP address and "Passed" status. All apple devices have also had their iOS updated to the latest version. All this has been done numerous times.
Its a pity that AirPrint used to work so fine. And now it doesnt. So the printer is useless since it cannot be wired to Apple Mac either.
Does anyone have a solution please?
Thanks. Ujbuk.
