Question about Fujifilm Instax Mini Evo

Once you have taken a photo, you can decide for yourself if and when you want to print the image.
If the cartridge is empty, you can still take photos.

Yes, this works as some users have already written. However, you can only upload photos to the app via the instax mini evo app that have also been printed. Very daft. Except save to SD card and then transfer the SD card to the PC.

Yes you can, the camera works like a normal digital camera. However, it is very much designed to print the photos afterwards in this small Polaroid format. This means that the image quality of the digital pictures is so-so. So if you just want to take photos and keep them digitally, I would recommend a different digital camera.

Yes, you can take pictures, look through them on the screen afterwards and print the ones you like.
