我有一个通过 samba 可用的网络打印机，我想在我的 Ubuntu 14.04 中使用它。不幸的是，仅仅通过打印机添加它是不够的。如果我尝试使用它，它会说：Connection failed: NT_STATUS_UNSUCCESSFUL然后Unable to connect to CIFS host, will retry in 60 seconds...
我该如何调试这些东西并了解它不起作用的原因？

答案1
也许它对某些人有帮助。
我在 Ubuntu 14.04 上遇到了同样的问题。以下步骤帮我解决了这个问题：
- 删除通过添加的打印机
System Settings->Printers localhost:631在浏览器中打开- 转到“管理”选项卡，单击“添加打印机”按钮并按照说明进行操作
我不知道为什么，但只有以这种方式添加打印机后它才对我和我的同事有用。
答案2
我通过修改打印机设备 URI 以包含用户名和密码来解决这个问题，格式如下：
smb://username:[email protected]/printer
（要更改此设置，请转到系统设置>打印机，然后右键单击打印机图标）
