How do I set my Samsung s7 camera to take photos at 300 dots per inch?

[AC Question]

I need to create a business card and retake an image on my camera. I have been advised by Vista print that I need to set the camera on the phone to 300 dots per inch but I dont know how to do this. If you can help that would be great.
