PHP打印-如何在本地服务器打印机上直接从PHP打印？

我想从本地服务器自动将文档打印到POS打印机

我试过迈克的方法，但没有用，这是我的代码

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Mike42\Escpos\PrintConnectors\FilePrintConnector;
use Mike42\Escpos\Printer;
use Mike42\Escpos\PrintConnectors\WindowsPrintConnector;
use Mike42\Escpos\CapabilityProfile;

class PrintReceipt extends Controller
{
   public function TestPrint(){
       $profile = CapabilityProfile::load("simple");
       $connector = new WindowsPrintConnector("LPT1");
       $printer = new Printer($connector, $profile);

       $printer -> text("Hello World!\n");

       $printer -> cut();

       $printer -> close();

   }

请参阅以下有关如何共享打印机的文章：




您可以在命令行上执行
echo“Hello World”>LPT1
？出于故障排除的原因，你在评论中写下了LTP1，应该是LPT1，假设这个打字错误与你的问题无关？@Eddy嗯，不是真的，它告诉我该文件找不到该文件。我该怎么办？@RoAchterberg编辑了这篇文章，我的错。打印机已连接并共享到LPT1端口。你是怎么决定的？
/**
 * Install the printer using USB printing support, and the "Generic / Text Only" driver,
 * then share it (you can use a firewall so that it can only be seen locally).
 *
 * Use a WindowsPrintConnector with the share name to print.
 *
 * Troubleshooting: Fire up a command prompt, and ensure that (if your printer is shared as
 * "Receipt Printer), the following commands work:
 *
 *  echo "Hello World" > testfile
 *  copy testfile "\\%COMPUTERNAME%\Receipt Printer"
 *  del testfile

/**
 * Connector for sending print jobs to
 * - local ports on windows (COM1, LPT1, etc)
 * - shared (SMB) printers from any platform (smb://server/foo)
 * For USB printers or other ports, the trick is to share the printer with a
 * generic text driver, then connect to the shared printer locally.
