这几天有空搞了下OPENWRT X86 15.05 cc的打印机共享

这几天有点空，手贱把当打印服务器的x86 openwrt从BB升到了CC，搞一了堆问题。。不知道ar71xx会不会也这样的情况呢。
话说我的HP M1005的一体机，打印功能在BB下是正常的，用的是p910nd的方式。升到CC后，竟然发现安装成功了，无法打印，不知道什么原因，打印机显示正在打印，就死在那里了。
无奈只得使用CUPS，不看不知道，一看吓死人，CC没有oldpackge的目录了，只能从BB里面一个个找过来，手工下载，还好硬盘空间足，随便下。
机器重启，下载的文件全丢了，这里凭记忆写一点了，希望有谁用得到。
大概是openwrt的wiki上说明的那样几个文件：http://wiki.openwrt.org/doc/howto/cups.serverRequired Packages
Server (OpenWrt)[td]

Name	Version	Size in Bytes	Description
cups	1.4.4-1	2 217 619	A printer spooling system for devices with USB or LP support.
zlib	1.2.5-1	39 388	Library implementing the deflate compression method
libpthread	0.9.32-65	30 717	POSIX thread library
libpng	1.2.44-1	128 723	A PNG format files handling library
libjpeg	6b-1	61 963	The Independent JPEG Group's JPEG runtime library
libstdcpp	4.3.3+cs-65	232 642	GNU Standard C++ Library v3
cups-bjnp	0.5.4-1	11 293	(optional) Description: CUPS backend for the canon printers using the proprietary USB over IP BJNP protocol. This backend allows Cups to print over the network to a Canon printer. It currently supports Cups 1.2 and Cups 1.3 and is designed by reverse engineering.

另外cpus里还要手工安装几个ppd文件，这是打印机描述的文件，相当于各种打印机描述文件，还有libcupsdriver。另外这里有个坑：有个lib版本不对，提示需要0.6.2，但我们安装的是0.9了，要去lib目录下做个软链接就可以启动cups服务器。
进入cups网页后，发现刷不出打印机来还有wiki上说的几个问题USB printers notes and throubleshooting

Backfire: There may be a problem interfacing with USB printers if usb-printers kernel module is also loaded. These conflict with the cups-provided USB support. There are plenty of bugs and one working solution is as follows:

• Remove usblp support: opkg remove kmod-usb-printer
• Edit user and group in /etc/cups/cupsd.conf from User Nobody/Group Nogroup to User root/Group root
• Change ACL on /usr/lib/cups/backend/usb to 700 (chmod 700 /usr/lib/cups/backend/usb). This changes the behaviour of cups, which normally tries to execute the backend through a user account other than root. This forces the backend to run as root from cups.
• Finally, it should be possible to add printers through the web page http://host:631/admin or manually. The USB device name cannot be displayed through lpinfo but can instead be listed by running /usr/lib/cups/backend/usb as root.
  

我因为是装过p910nd的，里面也有kmod-usb-printer,除了1以外，随便把3也做了，这样如4所说，cups的后端以root运行后，肯定能刷出打印机来。
最后，终于刷出了打印机，打印测试成功！
另外sane在这台一体机上用起来不爽，虽然说是支持的很好了，可客户端太烂，另外扫描的文档，会出现黄色的位置偏移，很难受，效果根本没有自带的好。不知道USBIP能不能解决这个问题？

弱问一下,现在哪个版本的X86 的支持打印? 也想把 旧工控机试试,省得打印机连我电脑.谢谢
