Windows 可以看到 Ubuntu Server 打印机，但无法打印到它

Question

我有一台旧台式机，正在尝试将其设置为家庭备份/打印服务器。备份很简单，但在打印工作时遇到了问题。打印机连接到运行 Ubuntu Server 9.10（无 gui）的服务器。如果我通过http://hostname:631/printers/访问打印机，我可以打印测试页，所以我知道打印机正在工作；但是，我在 Windows 中没有运气。

通过 \hostname\ 浏览时，Windows 可以看到打印机，但我无法连接。Windows 说“Windows 无法连接到打印机”但没有说明原因。

有什么建议？

您需要将来宾用户添加到 samba 密码数据库。通常这是通过guest在 samba 配置文件中映射到 UNIX 现有用户来完成的；通过组授予该用户打印权限；那么您应该能够通过\\server\URI 访问打印机。

您还可以尝试在添加网络驱动器时提供用户名（即管理员）来连接到服务器。
