Hi---hoping someone here has experienced this or knows what the issue could be....

While on the road I used to print with the iPad via a LAN set-up using an Airport Express router. Not sure if IOS 5 is responsible but possibly since the upgrade i am no longer able to do so.

Everything works fine in my home, meaning i can print from the iPad to both my HP D110 printer or non-Airprint HP Photosmart printer (using HP's printing app) with the same local network set-up. Where it doesn't work is at outside venues, like hotels, trade shows, museums, etc.,---public places with an abundance of smartphones or surrounding wi-fi signals.

Printing at these venues starts out fine but then it's suddenly like my wireless signal gets knocked out of the air or something. Printing freezes or stops at a quarter of a page or sooner.

Anyone know what this is about? Is this a new issue? And more importantly; is there any way to counter this?
