The device is really pleasant small. The photos appear pale, but are perfectly acceptable. But you should make any comparison with a real photo printer, here the device is decreased significantly. The size of printed photos was surprisingly small. Yes, of course, the dimensions are given here, but I have not measured it. That should do it ...
The app itself is of greater weakness. The possibilities here are sorely limited. However, it is always possible a photo aufzuhübschen in an external app and then to print the Druckapp. Then simply takes more time.
All in all, thanks to the ease of use and the previously known basically weaknesses (size of the printout, quality) four star.
