Hi @shlandrews,
Welcome to the community! I assume (as i could not confirm as i do not have an iMZ mobile printers where i could confirm) the latest version (v1.25.1) of the KoBoCollect android app should be compatible with ODK sensor (as ). I tried, using it and was able to reach till this stage:
But unfortunately, as i did not have an iMZ mobile printers i could not proceed further. Thus my hunch here is that if you follow the instructions laid out here, you should be able to print using the iMZ mobile printers.
Maybe some community members could confirm further!
Have a great day!
