我按照Debian的说明安装了CUPS：

apt-get install cups-client cups-pdf cups

然后启动CUPS服务/etc/init.d/cups start，然后尝试连接到http://localhost:631/，但firefox或w3m无法与之连接。

当我运行/etc/init.d/cups status时，答案是：

通用Unix打印系统的状态: cupsd正在运行。

我的操作系统是Debian Wheezy。

查看一下/var/log/cups目录。通常有3个文件是CUPS用来记录消息的：

access_log
error_log
page_log

示例

访问此目录将需要sudo。你可以这样做：

$ sudo head -5 access_log error_log page_log
==> access_log <==
