开发板上启动cups的命令为

/etc/init.d/cups stop/start

或service cups restart1.1.23

有时出现cups web管理界面没有响应，需要重启服务。开发板里面的cups目前为1.2.7版本，需要研究与高版本存在的差异。

3、手动安装的cups打印机的一些命令，范例：

/usr/sbin/lpadmin -p LaserJet -E -v parallel:/dev/lp0 -m laserjet.ppd

1.添加名为LaserJet的打印机(-p)

2.启用要使用的打印机(-E)

3.设置要使用的设备和设备类型(-v)

4.使用驱动程序／PPD文件laserjet.ppd (-m)

字符下打印：

/usr/bin/lp -d LaserJet /etc/aliases

lp语法将文件/etc/aliases打印到LaserJet打印机(-d)。

临时禁用和启动打印机：

/usr/bin/disable -r "Changing Paper" LaserJet

/usr/bin/enable LaserJet

CUPS配置

注意，不同的版本界面略有差异，本文所用的软件版本为1.3.9。cups在很多Linux版本中已自带，不需要额外安装。

进入Administration，点击“Add printer”。

选择正确的驱动程序，如果所连接打印机的驱动程序不存在，则必须手工添加驱动程序(略)。

在添加打印机的最后，会提示你输入Linux的root用户名和密码。

从下图可以看到新添加的打印机，名称为test。

重要提示：

1)打开选择administration，基本管理设置中Show printers shared by other systems，Share published printers connected to this system，Allow printing from the Internet这三项选定，即许可共享本地打印机，许可其它操作系统连接和许可网络打印。见【cups提供远程打印服务的配置经验】cups1.3.3。(好像并不是必须的)

2、编辑/etc/cups/cupsd.conf在Location选项添加容许的windows网段。

3、编辑/etc/cups/mime.convs，找到如下一行(很重要，否则会显示答应错误)

#application/octet-stream application/vnd.cups-raw 0 -

将注释去掉。

4、编辑/etc/cups/mime.type,找到如下一行(好像默认并没有注释)

#application/octet-stream

同3一样，将注释去掉。

1、Windows客户端

在使用cups连接的网络打印服务前，必须停止XP的防火墙服务，或添加631的协议。否则会引起问题的。安装步骤如下：

1)在弹出的对话框中选择“添加打印机”

2)选择添加的打印机类型为“网络打印机”

3)在URL下输入地址：，其中10.2.2.3为cups打印服务器的IP地址，631为cups服务端口，ll为添加的打印机的名称。

4)如果提示URL错误，请纠正。否则点击“下一步”，然后提供Windows下的打印机驱动即可。

以上配置在cups1.3.9下测试完成，不敢保证在cups其他版本是否一定通过。

2、Linux客户端

对于已联网并且安装了CUPS的Linux客户端来讲，能够自动检测到网络中的打印机。因此，只需要找到菜单“系统——>首选项——>更多首选项——>默认打印机>”(redhat enterprise server)或“桌面——>首选项——>更多首选项——>默认打印机>”(fedora)，将弹出网络上所有已存在的打印机，选择其中的某一在线打印机作为默认打印机即可。

网上提到在客户端要打开631端口或关闭防火墙，显然是错误的。应该是在服务器端打开631端口即可，是否关闭整个防火墙，笔者认为没有必要，不过调试过程中建议disable，以免对调试进度产生不利影响。

如果Linux客户端没有安装CUPS，则需要手工去添加打印机，笔者没有做过研究，网上有一篇文章(http://blog.sina.com.cn/s/blog_5507289e010008ky.html)，有兴趣的可以参考。

也可以使用samba服务来共享打印机，这是最常规的做法，只需配置samba服务，将打印机共享即可。

按照以上修改后，根据IP地址搜索计算机，应该可以找到打印服务器。

进入后能看到所有的打印机列表，选择其中一款打印机，点击连接即可。
