节点USB打印机

Question

任何人都知道如何为 Node.js 设置 USB 打印机。我无法为其配置界面。这是我的代码

enter code here const ThermalPrinter = require("../node-thermal-printer").printer;
                const Types = require("../node-thermal-printer").types;
                const electron = typeof process !== 'undefined' && process.versions && 
                                  !!process.versions.electron;

                async function testConnection () { 

                let printer = new ThermalPrinter({
                type: 'star',                                    
                interface: "Gold" //name of the printer
                });
                printer.print("hi");
                let isConnected = await printer.isPrinterConnected() 
                console.log("Printer connected:", isConnected);
                }
                 testConnection();

我跳出来的错误是在你的界面中。如果您使用 USB 端口，我建议您首先进行打印共享，然后通过修改值“interface”来配置您的节点终端打印机文件

1. 首先你进行打印机共享

2. 您修改指示路径和共享打印机的“interface”值

        `interface: '//localhost/printer',`
