 "escpos": "^3.0.0-alpha.6",
 "escpos-usb": "^3.0.0-alpha.4"

Steps To Reproduce

直接使用示例

npm init -y
npm install escpos escpos-usb
node index.js

const escpos = require("escpos");
// install escpos-usb adapter module manually
escpos.USB = require("escpos-usb");
// Select the adapter based on your printer type
const device = new escpos.USB();
// const device  = new escpos.Network('localhost');
// const device  = new escpos.Serial('/dev/usb/lp0');

const options = { encoding: "GB18030" /* default */ };
// encoding is optional

const printer = new escpos.Printer(device, options);

device.open(function (error) {
    printer
        .font("a")
        .align("ct")
        .style("bu")
        .size(1, 1)
        .text("The quick brown fox jumps over the lazy dog")
        .text("敏捷的棕色狐狸跳过懒狗")
        .barcode("1234567", "EAN8")
        .table(["One", "Two", "Three"])
        .tableCustom(
            [
                { text: "Left", align: "LEFT", width: 0.33, style: "B" },
                { text: "Center", align: "CENTER", width: 0.33 },
                { text: "Right", align: "RIGHT", width: 0.33 },
            ],
            { encoding: "cp857", size: [1, 1] } // Optional
        )
        .qrimage("https://github.com/song940/node-escpos", function (err) {
            this.cut();
            this.close();
        });
});

去node_modules里把usb.on那一段注释掉就可以了

You have to directly change a code line but this is not yet integrated into the official version check #428

I have battled with this library, even in the types, but I manage to work thanks to the comments, Python's is another case
