今天终于成功在Ubuntu7.10Server上成功测试了cups+hp1010
需要注意的地方记录下来：
缺省安装好Ubuntu之后，系统会出于安全考虑对CUPS系统进行限制，主要有以下几点：
1、不能通过Web界面 http://localhost:631/admin 对CUPS进行Web管理；
2、不能在其他机器上通过Web界面访问本机的http://localhost:631，以查看打印状态；
3、不能在其他机器上通过IPP协议来共享本机的打印机。
对上述三个问题，大家可以按照自己的需要做不同的设置：
1、造成该限制的原因很简单，由于cupsys用户没有访问/etc/shadow文件的权限，所以它无法识别用户真伪，要解决则很简单，只需要将该用户加入到passwd组中即可。命令如下：
$sudo adduser cupsys shadow
另：对打印机有管理权限的组是lpadmin组，所以如果要设立一个对CUPS系统有管理权的用户，只需要将该用户加入到lpadmin组即可，假设该打印管理员是firehare，那么只需要下列命令：
$sudo adduser firehare lpadmin
然后输入
$sudo /etc/init.d/cupsys force-reload
接下来我们试试在Firefox里输入：http://localhost:631/admin，然后输入超级用户或lpadmin组里的用户及密码均可进入到管理界面中。
以下是我的/etc/cups/cups.conf的配置文件

我这里是只允许192.168.1.110的机器来管理这台cups
呵，呵，就这么简单。
