the library doesn't have a method to open cash drawer. I'm using this to open the drawer instead:

const openDrawerBuffer = new Buffer(
['\u001B', '\u0070', '\u0000', '\u0025', '\u0250'].join('')
);
USBPrinter.printRaw(openDrawerBuffer.toString('base64'));

@lcang121 Hi thank you for your help.
please guide me.

1. which package you use for buffer
2. where i find this value ['\u001B', '\u0070', '\u0000', '\u0025', '\u0250']. for my cash drawer or this is static for all cash drawer

@komailabbas12 have you tried the COMMAD given by this library? like
import {
COMMANDS,
} from 'react-native-thermal-receipt-printer-image-qr';

COMMANDS.CASH_DRAWER.CD_KICK_2;
OR
COMMANDS.CASH_DRAWER.CD_KICK_5;
Let me know if this solutions works for you.
FYI @lcang121
