[原]再次处理cups 1.2.4打印问题

年初的时候，在Asianux 3.0上尝试配置cups 1.2.4打印服务，遇到不少问题。见这里：cups的windows-ext client-error-bad-request 故障。这天，由于工作需要，再次处理cups 1.2.4。莫名其妙的是，这次同样的故障居然只处理一次，所以，特留下配置文件待以后参考。

一、关于使用SSL连接
由于只在局域网内使用，而且使用的人员不多，就没有考虑SSL加密链接，并把其禁用掉了。
但一直觉得奇怪，为什么使用http://ip:631/访问正常，使用https://ip:631/访问就没有响应呢？根据cups提供的升级说明，1.2.4版本应该是支持自动识别加密或非加密连接的。
查看日志文件：/var/log/cups/error.log，发现，如果访问https://ip:631/，就会有如下提示：

决定等待试试，一直等。。。。等了5分钟后，终于出现：

I [06/Oct/2008:17:08:47 +0800] Started “/usr/lib/cups/cgi-bin/printers.cgi” (pid=16245)

原来是我耐性不够，cups在后台使用cgi程序会自动生成SSL证书的。
（这时候，用top也没发现相关的运行进程，故原以为浏览器已经停止响应了）

二、解决windows-ext client-error-bad-request故障
这故障没仔细研究如何解决的，仅知道现在已经可以正常通过Windows连接到cups上，并正常打印。
贴出配置文件：
