Ah,ok. Well I don't have a wireless printer but I also don't have Bonjour, so I guess that explains it. Thanks!

I just want to bring something to the developer's (and anyone else's) attention regarding this problem. I have a Mac and in my browser address line I kept entering the address listed under "For Apple computers" in the app but all my browsers came up with nothing. Wifi sync was fine. Then for the heck of it I tried the address listed under "For Windows computers" AND THAT WORKED. It seems the addresses are swapped in the app. You might want to examine this.
