I was printing quite happily from my i-pad 2 to my .HP1102W. I hadn't even done anything to set it up, that I remember. I didn't even need to switch the printer on. Then I moved to my other house. There I have an HP2540. I could still print from the iPad but it was relatively cumbersome. Every document I print I have to go to Settings, switch out of my network and switch into the printers network, after which switch out of that (I always forget) and back into my iPad's network to use Safari or whatever. Now back in the old house things have changed. It doesn't print automatically without these manipulations like before. In settings there is a new bar called 'devices' and it seems to know about HP though not the model. When I try even the long proceedure above it fails to find an air printer. I did manage to find it once today and print a page - I don't know how. I would like to be able to make both printers (1) work (2) preferably in the immediate fashion the 1102W did before (3) every time. How?
