Is it possible to start barcode scanning from python on a barcode scanner?

I have a barcode scanner, and currently, it is working as a keyboard so if the scanner successfully scans by pushing the trigger the scanned code goes to the computer as input.

Now, I want to write a python program on my Raspberry Pi 3B which connects to the scanner and start the scanning process without the need of pushing the trigger on the scanner. Meaning that I make a GUI where only by just clicking on a button the user starts the scanning process and the scanned code (if the scan was successful) gets outputted.

The question is: how to do it?

I have tried pyusb but it can't send a command to the scanner to scan (Or I don't know how).

Even worse if it turned out that there is nothing like Python-Scanner communication, only the primitive connected || not connected type.

Depending on which operating system you use, you should look into the SDKs for the scanner you're using. It seems they provide some tools to control the scanner. They a re not very informative on what exactly they support though. ( for example: https://www.zebra.com/us/en/support-downloads/software/developer-tools/scanner-sdk-for-linux.html)

The reference manual for the serial interface I found here: https://www.zebra.com/content/dam/zebra_new_ia/en-us/manuals/barcode-scanners/Simple%20Serial%20Interface%20Programmer's%20Guide.pdf
