Re: Android printing - a fail
Further to that last, it seems to be the proprietary boys taking the lead here.
I just took possesion of a shiny, new Acer Iconia Tab A510. One of the things that came with it is "Acer print", which also happily tied itself to my wireless printer.
That one seems to be generic. It may be worth seeing if you can track it down and run it on a non-Acer device too.......
 Odd thing about this beastie, much of the bundled Acer-specific stuff is actually useful. Top marks to Acer for providing useful enhancements with their toys rather than the usual pointless cruft.
