Retina Display + Print Quality

Hi, this app is great but whats missing is that (1) for it to be improved to the retina HD display. (2) Also when i use this app to print documents, they usually come with lower printing quality than when i print the exact same ones from my macbook pro! Could you plzz fix these small issues? i will be so grateful..
