We have tools setup that run via a Progressive Web Application in React via Google Chrome. We want to be able to send very rudimentary text information via API call to our .Net backend and then print directly to a ZQ620 printer. This application is used in a warehouse setting and thus minimizing user interaction with the device is important. Thus, we want to print directly from the server to bypass the confirm pop-up and the need to generate a preview.
I use Zebra ZQ220 printer. When I send text from Android via bluetooth to printer in russian languge:
! 0 200 200 200 1
TEXT 14 0 20 80 Привет мир
I have in result something like this:
How I can fix this?
Getting Could not disconnect from device: USB Connection failed to release.
