Cannot print from android app because of bluetooth connection

Hi, I am ahaving problems when printing from an Android app.
I have my app in a yoga tablet working fine but It does not work with a lenovo tab 10 with android 9.

With my lenovo tab 10 I can pair the printer correctly but whenever I want to print it tells me that I need to connect the printer to my device. I go to settings, I select the printer I click in connect but nothing happens

WT6000 (Nougat) where is voice recognition

I am developing an application using Xamarin on an WT6000 that is now running Nougat.
It seems that all of the Google voice recognition apis are missing…
How do I utilize speech or voice recognition services on this device?

Is there another app/utility/api that CAN be used on this device to enable voice recognition integration?
Specifically, I am looking to do speech to text to my app.

Thanks in advance!
