Printer Support Apps Should Do One Thing:

... act as a printer driver for other apps

The kyocera app only appears to other apps in a "Copy To..." capacity. That means that many apps that can ordinarily print via AirPrint will not even see the Kyocera app. It also means that the Kyocera app imposes its own rendering on apps that can copy to it (for instance, forcing portrait mode when you want landscape mode).

The rest of the file opening and saving mechanisms are extraneous and ill conceived.
