App works but it’s all in Japanese
The app works fine, I was able to print at family mart in Japan. It’s just all in Japanese so I’d recommend making screenshots and feed these to the Google translate app, to read what the buttons mean.
Doesn't work at my family mart
My local shop requires printsmash which is not available in my region app store 😔
Not for internet-connection printing
This app does work, but only for “network printing.” Open a document or picture (you can access your phone’s files by pressing the orange button on the bottom row) in the app, select your size, then press the upload button. It will show a number that you can enter into a family mart printer if you select “network printing.” Rather difficult to navigate, but still a functional app.

Does not work
This app does not actually connect to the machines at FamilyMart in Japan. For that, you must use Print Smash, which is unavailable on the US App Store.
