Is it possible to print from an Android device (Samsung Galaxy Tab 3) via mini-USB to USB adapter?
First of all, the device should have enabled the OTG in software and of course available as hardware. The other thing, that it misses is Drivers for sure. Maybe you could print out some photos from your phone, if there is an option to connect it as a PTP device directly to your printer, if your printer offers printing through PTP interface.
