I recently updated itunes to the latest version, downloaded and installed airprint and bonjour on my windows 7 64 bit pc to print to my non-airprint Epson Artisan 800 from my Iphone 5s with OS 7.0.4. I am using a Linksys E2500 router also. All works well for a few minutes then I lose the printer from my Iphone. Upon restarting Airprint services it immediately pops back up on the Iphone for those few minutes again. I have done several things I found in other forums to supposedly fix this problem to no avail. Any help is appreciated.
I am having similar issue but on a large scale. I have only a few printers that drop off while others stay. I notice this on my iOS devices, but if I check my macbook they all still display, so only on iOS devices it is disappearing.
