Ionic Native "Serial" plugin not working for USB OTG connected printer

I’m using this plugin ( for USB OTG connected printer. But the plugin is not working. It always executes .catch() on requestPermission. Some native android apps from PlayStore perfectly detects it and prints well but I have not found any plugin from Ionic to perform this task. Please help

N.B. I have already tried ionic-native Printer plugin but it was not working as it tries to find Wireless or network printers.

Hello i have the same issue, did you find any solution ?

Did you get any Error Messages in the Catch?

I tried all the listed drivers got the same error message (No device found)
-> I’m trying to connect to a printer !

I am also facing the same issue. But it is unable to find the device.
