Q: Can't airprint from IOS 6   error:No AirPrint printers found

I too am having this same problem...only I'm using an HP printer.  It used to work albeit, I didn't really use it that often.  And it was working prior to IOS 6.  Fortunately, I'm getting around the issue by using the Eprint app that HP offers.  I can only wonder how many out there DON'T know whether or not this feature is in fact working with the latest IOS updates.

Yes, it is working with the latest updates.

Thanks for confirming Deggie

Here is a link to the HP Eprint App that Denny mentioned to allow him to print via airprint to his HP Printer

Just wanted to update my original post.  Turns out that my DSL modem was the problem.  I've been having issues with internet disconnects at randum.  So to fix, I've replaced my modem and all is well   Airprint works just fine on all of my IOS devices.

I also cant' airprint from IPad, IPhone. I can in Safari connect to the printer 192.168.... (See Printer Config). I can also print reports from there. but I cant find the Printer, to print pictures, docs...

Printing from android(Iprint app) or win8 works fine.

Printer ist brother HL-5470DW on same Wlan, Airprint is active. everthing reseted view times, printer firmeware new 1.11 Ipad upgraded to mountain lion.

still hopeing

I'could solve the problem by disabling 3G. After that the Printer worked fine, and then I enabled 3G again and it still worked (wonder).

And also the Ipad prints know. There I do not have 3G (only wlan). Therefor I enabled Flightmodus and then I disabled flightmodus again. That works so far. Not to forget of course, to switch everything off power first, wait a few minutes an start router first and then printer, Ipad, Iphone.
