阅读14分钟换路由器或路由器重启后，主机被路由器重新分到新 IP，客户端却还按旧地址去连，所以共享打印机变脱机、不可用。以下方法在 Windows 10/11 实测可用。
先在主机执行 ipconfig /all 查到新的 IPv4 并记下 hostname，在客户端 ping 通；再删掉旧连接用 \\新IP\共享名 重加；更稳的做法是改用 \\主机名\共享名，或者在路由器里给主机做一个 IP-MAC 静态绑定。
多数情况是地址变化和旧连接残留造成的，网卡、打印机这些硬件大多没坏，不必急着重装系统或送修。
适用系统：Windows 10/11；最后更新：2026-10-27。
换了路由器，共享打印机为什么突然就连不上了
换完路由器当天，客户端点那台共享打印机，Windows 弹出「Windows 无法连接到打印机」，详细信息里写着「操作失败，错误为 0x80070035」，有时是 0x0000007e。主机上这台打印机打测试页照样正常。

先确认主机的地址有没有变，再决定是删掉旧连接重加，还是干脆改用主机名连接，能省下反复卸载重装驱动的时间。
方法1 在主机上查出打印机现在的新IP并ping通
主机地址被路由器重新分配后，第一步是先在主机上拿到当前 IPv4 和计算机名，再在客户端 ping 通，先确认两台机器在同一个网段。
操作步骤
- 在共享主机上按 Win+R，输入 cmd 回车，打开命令提示符。
- 执行 ipconfig /all，找到当前网卡那一项下面的 IPv4 地址（常见是 192.168.1.8 这类）和默认网关，用纸记下来。
- 在同一个窗口执行 hostname，记下主机的计算机名（如 DESKTOP-ABC），方法3 要用到。
- 回到客户端，Win+R 输入 cmd，执行 ping 192.168.1.8，能收到「来自 192.168.1.8 的回复」说明两台机器可通。
- 再执行 ping DESKTOP-ABC，通了说明局域网里的名称解析正常；ping 不通就先看两台机器是不是连的同一个路由器，有没有一台连到了访客网络，或者连的是 2.4G 与 5G 分开的那个 Wi-Fi。

方法2 客户端删掉旧连接，用新IP重新添加共享打印机
客户端里留着的那条记录还是旧地址，光点重连没用，要先把脱机的旧连接删干净，再用 \\192.168.1.8\HP1108 重新连一次。
操作步骤
- 打开 设置→蓝牙和其他设备→打印机和扫描仪，选中那台共享打印机，点「删除设备」。
- 再到 控制面板→设备和打印机，如果还残留同一台，右键→删除设备，把旧打印队列一起清掉。
- 到主机的 打印机属性→共享 页，确认共享名（如 HP1108），共享名尽量别带空格和中文。
- 客户端 Win+R 输入 \\192.168.1.8\HP1108 回车，开头是两个反斜杠，别写成单斜杠。
- 在弹出的共享打印机上右键→连接，等系统自动装好驱动，装完打印一张测试页确认。
- 跳出凭据窗口就填主机上的本地账号和密码，勾选记住凭据；若提示 0x80070035 找不到网络路径，回方法1 核对 IP 和共享名有没有敲错。
方法3 改用计算机名连接并在路由器做IP-MAC静态绑定
按 IP 连，路由器一换或一重启就可能再断一次；改用 \\主机名\共享名，再把主机地址在路由器里固定下来，这件事才算真的解决。
操作步骤
- 客户端 Win+R 输入 \\DESKTOP-ABC\HP1108 回车（主机名前也是两个反斜杠），在共享打印机上右键→连接。
- 浏览器打开路由器管理页，地址就是主机 ipconfig 里显示的默认网关，常见是 192.168.1.1 或 192.168.0.1，登录账号密码一般贴在路由器底部。
- 登录后找到「DHCP 地址保留」「静态地址分配」或「IP-MAC 绑定」这一栏。
- 填上主机网卡的 MAC 地址（主机执行 ipconfig /all，看「物理地址」那一行），绑定一个固定 IP，比如 192.168.1.5，保存后重启路由器。
- 回主机执行 ipconfig /release，再执行 ipconfig /renew，确认重新拿到的还是绑定后的那个地址。

用「软领打印机驱动修复大师」更省事
上面这几步要在主机和客户端之间来回切，手敲 IP、核对共享名、翻服务列表，哪一步敲错都得从头再来。软领打印机驱动修复大师里的「打印机共享」就是干这件事的：它提供「共享我的打印机」和「连接共享打印机」两个入口，主机端把打印机共享出去，客户端直接连过来，不用再去记 \\192.168.1.8\HP1108 这串地址。把逐项比对 IP、共享名和服务状态的活交给它，共享链路连回来之后，客户端再连一次主机就行。
它还带着共享环境检测，会把主机和客户端在不在同一个网段、共享有没有打开列出来。路由器换了地址，哪一头对不上，一眼就能看出来。

方法4 回主机检查共享设置、共享名和打印后台服务
地址已经对上了还是连不上，问题多半在主机这一侧：共享没打开、共享名对不上，或者 Print Spooler 服务被停掉了。
操作步骤
- 控制面板→网络和共享中心→高级共享设置，在当前网络下打开「网络发现」和「文件和打印机共享」。
- Win+R 输入 services.msc，找到 Print Spooler，确认状态是「正在运行」，没运行就右键→启动，并把启动类型改成自动。
- 同一个窗口里确认 Function Discovery Provider Host、Function Discovery Resource Publication 这两个服务也已经启动。
- 主机上打开 打印机属性→共享 页，勾选「共享这台打印机」，把共享名记牢。
- 控制面板→Windows Defender 防火墙→允许应用通过防火墙，在列表里勾上「文件和打印机共享」。
- 出现 0x0000011b 一般是主机端 RPC 打印相关补丁的限制，主机和客户端都把系统更新装齐，重启后再试。

方法5 清掉旧凭据并重置网络组件（兜底）
主机换过地址或换过账号之后，客户端残留的凭据和网络栈也会挡着连接，这一步把它们清干净再连。
操作步骤
- Win+R 输入 control keymgr.dll 打开凭据管理器，在「Windows 凭据」下删掉指向旧主机名或旧 IP 的条目。
- cmd 里执行 cmdkey /list 查看已保存的全部凭据，必要时用 cmdkey /delete:旧主机名 删掉那一条。
- 以管理员身份打开 cmd，执行 net stop spooler 停掉打印后台服务，再执行 net start spooler 启动。
- 依次执行 ipconfig /flushdns、netsh winsock reset、netsh int ip reset，执行完重启电脑。
- 重启后再 Win+R 输入 \\主机名\共享名 连一次；还是不行就换另一台客户端试，用来判断是主机侧的问题，还是这一台机器自己的问题。
大家常问
win11共享打印机换路由器后提示0x80070035找不到网络路径怎么办？
这个码的意思是客户端按老地址找主机，路径已经不存在。回主机执行 ipconfig /all 记下新的 IPv4，客户端 ping 通之后，删掉旧设备再用 \\新IP\共享名 重新添加；还要确认主机上「网络发现」和「文件和打印机共享」是打开的。
打印机ip地址怎么查？主机IP变了共享打印机脱机怎么恢复？
在主机上 Win+R 输入 cmd，执行 ipconfig /all，看当前网卡那一项下面的 IPv4 地址，那就是打印机所连主机的地址。恢复方法是客户端先把脱机的旧设备删掉，清掉旧打印队列，再用新 IP 重新连一次。
Win11 里 \\主机名 能连上、\\IP 却连不上是什么原因？
说明局域网里的名称解析是好的，问题出在主机地址变了，而客户端的记录还是旧 IP。把连接方式改成 \\主机名\共享名，同时在路由器给主机做 IP-MAC 静态绑定，这条连接就不会再随地址变化断掉。
共享打印机报0x0000011b错误代码怎么解决？
这类报错通常和主机端 RPC 打印相关补丁的限制有关。主机和客户端都装齐系统更新，重启两台机器再连一次；仍然不行就按方法4 逐项确认共享名与 Print Spooler 服务状态。
路由器重启后共享打印机又断了，怎么让主机IP固定不变？
进路由器管理页，找到「DHCP 地址保留」或「静态地址分配」，按主机网卡的物理地址绑定一个固定 IP，比如 192.168.1.5。绑定完成后主机执行 ipconfig /release 和 ipconfig /renew，之后用 \\主机名\共享名 连接。
