阅读17分钟戴尔电脑连接共享打印机失败，多数是 Print Spooler 服务停止、C:\Windows\System32\spool\PRINTERS 目录有卡死任务、Windows 安全更新收紧注册表 RPC 策略（报错 0x0000011b / 0x00000bc4）或共享端防火墙配置漏项引起的，打印机硬件本身大多没有损坏，不必急着送修。
按从易到难依次处理：①重启并固化 Print Spooler 服务；②清空 PRINTERS 目录卡死文件；③修复 0x0000011b 注册表键值；④核对共享端设置与防火墙；⑤检查网络发现与 SMB 协议。以下方法在 Windows 10/11 实测可用，修好即停。
适用系统：Windows 10/11；最后更新：2026-06-22。
戴尔电脑连接共享打印机失败是什么情况
在局域网内用戴尔电脑添加已共享的打印机时，系统常弹出「Windows 无法连接到打印机」「本地打印后台处理程序服务没有运行」，附带错误码 0x0000011b（源自 Windows 10/11 2021 年 KB5005565 安全更新后的 RPC 认证策略变更）或 0x00000bc4（客户端找不到共享打印机服务）。打开 services.msc 可发现 Print Spooler 处于已停止状态，或服务启动后因 C:\Windows\System32\spool\PRINTERS 目录内的损坏队列文件再次停止。出错方向集中在服务、队列、注册表策略和共享端配置几个层面。

方法一 重启并固化 Print Spooler 服务
Print Spooler 是 Windows 管理本地和网络打印任务的核心服务，该服务一旦停止，客户端便无法搜索或连接任何打印机，包括共享打印机。将它启动并设为"自动"启动类型，重启后不会复发。
操作步骤
- 按
Win + R，输入services.msc回车，打开服务列表。 - 找到 Print Spooler，右键 → 属性，将"启动类型"改为自动，点"启动"→"确定"。
- 也可在管理员命令提示符执行：
sc config spooler start=auto，再执行net start spooler。 - 返回"设备和打印机"重新添加网络打印机，确认是否恢复正常连接。
Spooler 服务启动后，客户端通常可以在「添加打印机」向导中搜索到局域网内的共享队列。整体排查从易到难分五个层次，层层递进定位问题。

方法二 清空 PRINTERS 目录内卡死的队列文件
当 Spooler 意外崩溃时，C:\Windows\System32\spool\PRINTERS 目录内会残留损坏的 .SHD 和 .SPL 队列文件，下次 Spooler 启动时这些残片会阻止服务正常初始化，进而导致共享打印机连接一直失败。清空该目录后服务才能正常接受新的打印任务。
操作步骤
- 以管理员身份打开命令提示符，执行
net stop spooler停止 Print Spooler 服务（也可在services.msc右键"停止"）。 - 打开资源管理器，导航至
C:\Windows\System32\spool\PRINTERS，全选目录内所有文件并删除（子文件夹本身保留不删）。 - 执行
net start spooler重新启动服务。 - 再次尝试添加或连接共享打印机。
清空 PRINTERS 目录不会影响已安装的驱动或打印机配置，操作完成后打印机列表保持不变，可放心执行。Spooler 启动后的状态决定下一步：持续运行说明服务本身已恢复，直接重试连接；若立即再次停止，则说明队列文件仍有残留，重复清空步骤直至服务稳定。

方法三 修复 0x0000011b 注册表键值
错误码 0x0000011b 在 2021 年 10 月之后的 Windows 10/11 上大量出现，根因是微软安全更新（KB5005565 / KB5005566）默认启用了 RPC 认证加密，导致旧版共享打印机连接被系统拒绝。在注册表中将该强制策略关闭即可恢复连接，操作仅影响局域网内可信的打印机共享路径。
操作步骤
- 按
Win + R输入regedit回车，打开注册表编辑器。 - 导航至
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print。 - 在右侧空白区域右键 → 新建 → DWORD（32 位）值，命名为
RpcAuthnLevelPrivacyEnabled。 - 双击该键，将数值数据改为
0，点"确定"。 - 重启电脑，再次连接共享打印机验证是否恢复。
此注册表操作仅适用于局域网内可信共享场景；跨公网访问打印机建议通过 VPN 隧道连接，不直接修改 RPC 验证策略。修改前后的状态变化如下图，对照确认键值已正确创建。

方法四 核对共享端打印机设置与防火墙
共享打印机的连通性依赖共享端（安装打印机那台电脑）正确开放共享并让防火墙放行。任意一项缺失，客户端都会持续提示"Windows 无法连接到打印机"，前三步即使都做了也会失败。
操作步骤
- 在共享端打开"设备和打印机"，右键目标打印机 → 打印机属性 → 共享 → 确认"共享这台打印机"已勾选，记下共享名称（如
DL_LJ）。 - 打开共享端的
services.msc，确认 Print Spooler 状态为"正在运行"。 - 打开共享端 Windows Defender 防火墙 → 允许的应用 → 勾选"文件和打印机共享"，确保专用网络与公用网络均已启用。
- 在客户端（戴尔电脑）按
Win + R，输入\\共享端IP\共享名称（如\\192.168.1.10\DL_LJ）回车，弹出凭据框时输入共享端账号密码。 - 右键弹出的打印机图标 → 连接，驱动安装完成后即可正常打印。
共享端 IP 可在命令提示符执行 ipconfig 查看；确保戴尔客户端与共享端在同一子网（IP 前三段相同），否则还需检查路由器或交换机的子网配置。
方法五 检查网络发现与 SMB 协议设置
如果前四步均未解决，通常是客户端或共享端关闭了"网络发现"功能，或 SMB1 协议被系统策略禁用，导致局域网内的打印机共享资源根本无法被枚举，连接路径永远找不到目标。
操作步骤
- 在戴尔客户端打开"控制面板 → 网络和共享中心 → 更改高级共享设置"，展开"专用"与"来宾或公用"，将"网络发现"与"文件和打印机共享"均设为启用，保存更改。
- 在管理员 PowerShell 执行
Get-SmbServerConfiguration | Select-Object EnableSMB1Protocol，若结果为 False，共享端需运行Set-SmbServerConfiguration -EnableSMB1Protocol $true -Force（Windows 10 21H2 及以上默认禁用 SMB1，旧款打印机依赖 SMB1 时才需开启）。 - 若仍无法枚举共享，在共享端执行
gpedit.msc→ 计算机配置 → Windows 设置 → 安全设置 → 本地策略 → 安全选项，将"网络访问：不允许 SAM 账户的匿名枚举"改为已禁用。 - 重启共享端后，客户端再次用
\\IP\共享名重新连接。
跨不同 Windows 版本共享（如 Windows 7 共享端搭配 Windows 11 客户端）时，SMB 协议版本不匹配是最常见的隐性阻断点，按上述步骤核查版本兼容性即可定位。

常见问题
戴尔电脑连接共享打印机提示 0x0000011b 怎么办？
这是 Windows 安全更新（KB5005565）修改了 RPC 认证策略导致的。在注册表 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print 下新建 DWORD 值 RpcAuthnLevelPrivacyEnabled 并设为 0，重启后可解决，适用于 Windows 10/11 局域网共享场景。
戴尔电脑提示"本地打印后台处理程序服务没有运行"怎么修？
按 Win + R 打开 services.msc，找到 Print Spooler，右键启动并将启动类型改为"自动"，防止下次开机服务未能自动启动。
共享打印机添加成功但打印没有反应是什么原因？
多数是 C:\Windows\System32\spool\PRINTERS 内有卡死文件堵住了队列。停止 Spooler 服务后清空该目录再重启 Spooler，一般可恢复正常打印。
戴尔电脑用 \\IP\打印机名连接时弹出凭据框，应填什么账号密码？
填写共享端（安装打印机那台电脑）的 Windows 账户名和登录密码。若共享端未设密码，可尝试只填账号名、密码留空；或在共享端调整共享权限，允许 Everyone 读取。
戴尔电脑连不上共享打印机，其他品牌电脑正常，是什么原因？
通常是该台戴尔电脑的 Print Spooler 状态异常、网络发现未开启，或安装了不同版本的安全更新导致 RPC 策略与共享端不一致，按本文方法一到方法三逐步排查即可定位。
