操作步骤
- 查看打印机正面或背面铭牌，记录完整型号和接口类型。
- 打开「设置→系统→系统信息」，确认 Windows 版本和系统类型。
- 按完整型号搜索官方支持页，选择对应系统位数的打印机驱动。
- 下载后放到英文路径，例如
C:\Drivers\Samsung4521。
方法二，清理旧驱动和残留端口
旧驱动残留会让系统误判三星 4521 已安装，表现为安装包回退、设备不可用，或打印机列表里出现多个灰色设备。
操作步骤
- 打开「控制面板→程序和功能」，卸载旧的 Samsung 打印机驱动和扫描组件。
- 按
Win+R输入printui /s /t2，进入打印服务器属性。 - 在「驱动程序」中删除旧的 Samsung 4521 相关驱动包。
- 重启电脑后再进入下一步，避免旧端口继续占用。

操作步骤
- 拔掉 USB 线，确认打印机电源已开启。
- 右键驱动安装程序，选择以管理员身份运行。
- 安装程序提示连接设备时，再将 USB 线直插主机接口。
- 安装完成后打开「打印机和扫描仪」，将三星 4521 设为默认打印机。
方法四，修复打印服务和兼容环境
老机型驱动可能依赖系统组件，若安装后仍提示驱动不可用，先修复 Print Spooler，再尝试兼容模式。
操作步骤
- 按
Win+R输入services.msc，确认 Print Spooler 为自动并正在运行。 - 以管理员身份执行
sfc /scannow，等待系统文件检查完成。 - 继续执行
DISM /Online /Cleanup-Image /RestoreHealth。 - 若驱动较旧，右键安装包打开「属性→兼容性」，选择 Windows 10 兼容模式后重试。
常见问题
三星4521打印机安装步骤里先插 USB 吗？
建议先运行驱动安装程序，等提示连接设备时再插 USB 线，避免系统提前加载错误驱动。
三星打印机4521驱动怎么安装到 Windows 11？
先确认 64 位驱动来源，再清理旧驱动；旧安装包可用兼容模式运行，但要保留管理员权限。
代码 28 出现在三星4521上怎么处理？
代码 28 表示驱动没有正常安装，先删除旧驱动包，再按完整型号重新安装。
三星4521需要用 DDU 卸载驱动吗？
通常不需要，DDU 更偏向显卡驱动；打印机驱动用打印服务器属性删除更对路。
