Great Printer Apps with small weaknesses

Did this app may be acquired as a free on Amazon. Thanks a lot for this!
The setting up my printer Canon MG6350 was performed without problems and also the first test expression convinced. However, when photo printing on the Fomat 10x15 (postcards size) I have thin on 2 sides of the picture frame, white borders. Even multiple settings (rimless, ...) could not solve this problem, unfortunately. Also have no way when printing PDF documents to use on A4 setting duplex printing. Too bad!
Nevertheless, for fast Audrucke from email and Co a very compelling app that I do not want to miss.
