How does photography print out photos?

I'm a photographer, and your question is simple. First of all, the computer installs a software called flattery, and you can connect the camera with the computer by downloading an app through your mobile phone. Then the computer flattery software will combine your pre-designed template with every photo beautification (such as ps peeling and whitening). After that, it will be assigned to one or more printers. It is thought that a printer needs ten or twenty seconds to print a photo, so some will be equipped with two or three printers.
