How to activate auto cut on a pos printer?

Hi experts, code below is working and could able to print. However, I'm looking for a solution how to activate auto cut base on the codes given below. My pos printer has an auto cut function and I want to activate it. Any help please!

Js

  function ePrint(){
  	const {PosPrinter} = require('electron').remote.require("electron-pos-printer");
  	const print_data = [
  		 {type: 'text', value: 'Header', style: 'text-align:center;font-size:19px;'},
  		 {type: 'text', value: 'Sample 2', style: 'text-align:center;font-size:14px;'},
  		 {type: 'text', value: 'Sample 3', style: 'text-align:center;font-size:14px;'},
  	];
  	PosPrinter.print(print_data, {
  		 printerName: 'EPSON TM-U220 Receipt',
  		 preview: false,
  		 width: '100%',               
  		 margin: '0 0 0 0',            
  		 copies: 1,                   
  	 })
  	 .then(() => {
  		 //Activated auto cut
  	 })
  	 .catch((error) => {
  		 console.error(error);
  		});
  }

For those types of printers you are giving using escape commands and each printer company has their own proprietary functions.

Review https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=72 and https://files.support.epson.com/pdf/pos/bulk/tmu220_rsu_guide_reva.pdf

First thing is to determine the exact printer you have. I see from your code you are using but according to the pdf file I linked to, "On TM-U220 Type D, use the “GS ( z 2 0 0 E“ command to terminate and print the defined block because TM-U220 Type D doesn’t have an autocutter."

I don't see in your code where you are giving the esc codes. You must be using a library because the code you are showing would not work on it's own. The first step is to determine that your printer has the ability to cut. The next is to look at the docs specific for your printer as there are different cut options. Then review the docs for your js library on how to submit the esc code or the cut command may already be built in to your library especially if it is meant for epson?
