A:Answer I'm not certain about WeChat, as I don't use it in particular, but the web app should allow printing as you use can the built-in browser Print function to initiate a print job. The mobile app may if the app allows you to select images, and shows you a print option with the built-in iOS and Android print plugins, or if the app has a Print function built-in.
It can print remotely using Google Cloud Print.
