基于PHP的印刷网站源码，提供了一套完整的线上印刷服务解决方案。该源码包含用户界面设计、订单处理、支付系统集成以及后台管理等功能，旨在帮助印刷企业快速搭建自己的在线服务平台，实现业务的数字化转型。

由于回答长度限制，我将提供一个简化版的PHP印刷网站源码示例，这个示例将包括一个简单的用户注册和登录系统，以及一个用于显示印刷产品列表的页面，这只是一个基本的示例，实际的网站可能需要更多的功能和安全性考虑。

<?php
// config.php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "printing_db";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn>connect_error) {
    die("Connection failed: " . $conn>connect_error);
}
// register.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    $sql = "INSERT INTO users (username, password) VALUES ('$username', '$password')";
    
    if ($conn>query($sql) === TRUE) {
        echo "Registration successful!";
    } else {
        echo "Error: " . $sql . "<br>" . $conn>error;
    }
}
// login.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    $sql = "SELECT id FROM users WHERE username='$username' AND password='$password'";
    $result = $conn>query($sql);
    
    if ($result>num_rows > 0) {
        session_start();
        $_SESSION["loggedin"] = true;
        $_SESSION["username"] = $username;
        header("location: products.php");
    } else {
        echo "Invalid username or password.";
    }
}
// products.php
if (!isset($_SESSION["loggedin"]) || $_SESSION["loggedin"] !== true) {
    header("location: login.php");
    exit;
}
$sql = "SELECT * FROM products";
$result = $conn>query($sql);
?>

        </tr>
        <?php endwhile; ?>
    </table>
