I get access denied error trying to run .open() function.

@hayyaun Try to remove VENDOR_ID filters

I actually did it, and also removed getDevices(), but it's not working... the error is on the .open() part.
It's a label printer. I guess there is no usb communication defined for this type of printer? I don't know where to look for docs... there is no any

I hope you run the script in Google Chrome. You can see the documentation here https://wicg.github.io/webusb/

Put a catch exception, see the error. Unfortunately, I can't help you any more, I don't have this model

hayyaun commented

catch shows Uncaught (in promise) DOMException: Failed to execute 'open' on 'USBDevice': Access denied.

I just found out windowsOS needs to rename its modules using zadig app to get working with usb printers.
