Did you have to download anything besides the app ? I am using printershare, but GS3 tells me I need to download a driver pack from "mobile dynamix", but can't provide me a link to use. My phone knows the printer is there, but they can't communicate. My first experience with wireless direct, and I must say I am not impressed so far.
I AM TRYING TO USE THE FREE PRINTERSHARE APP. COULD THIS BE THE PROBLEM ??
