I too have my printer plugged directly into my router, but again, I am also on a Mac when it sounds like you may be on a PC so maybe that's the difference. Otherwise, I'm not sure at all as to why PrinterShare won't launch anymore, but when it did, I remember ALWAYS having to login first on my Mac to get it to work. That's what I'm hoping to avoid if finding an Android app that will allow me to connect using just the Bionic and a wifi connection (and NO desktop apps/logins).
Thanks also to all others who have responded to this post. Since a few of you seem to really like Cloud printing I may just go ahead and give it a try...again, I am just very concerned about privacy issues so I guess I'll make sure NOT to print any private email messages or bank statements etc. until I find out for sure how secure it is.
