I need PrintConnect and Zebra Printer Utility apps for Android 8

We have ​about 150 Samsung tablets. Some of them have Android 8.1 and can't be updated more than that, and we use Zebra PrintConnect and Zebra Printer Setup Utility apps a lot, so my question is, is there any way we can download an older version of both apps that works with Android 8.1? 

Please let me know.​ 

Thank you very much

Have a Blessed Day
