Usage

Printing

You can print a simple text using the method printStr(text:string, cutMode?:number):void

cutMode is an optional parameter to tell the printer how it should cut the paper (partially, fully or no cutting at all) after finishing printing.

If the parameter cutMode is not set then the printer will cut the paper fully.

Full Cut : Pax.FULL_CUT
Partial Cut : Pax.PARTIAL_CUT
No Cutting : Pax.NO_CUT

default: Pax.FULL_CUT

import Pax from "react-native-pax-library-pos";

// ...

Pax.printStr("Hello World", Pax.PARTIAL_CUT);

Opening Cash Drawer

If you have a cash drawer linked to your Pax device, you will be able to open it automatically using the method openDrawer(): Promise<any>

The result returned from this method is a promise that resolves with the result 0 if it succeeds.

// ...

try {
  const result = await Pax.openDrawer();
} catch (error) {
  console.error("Unable to open Cash Drawer.");
}
