用的打印机放置的比较远，而且没有专门的打印电脑，为此需要架设局域网共享打印

这里选择了BeagleBone-Black作为终端，已经烧录Debian系统，用网线连接至局域网，USB插入HP LaserJet 1020打印机数据线

（翻找出来的BBB）

0.设备与环境

BeagleBone-black（简称BBB），运行Debian系统
HP LaserJet 1020打印机，数据线插在了BBB的USB接口上
个人电脑上需安装HP LaserJet 1020打印机驱动

1.BBB上配置

a.安装HPLIP、CUPS

HPLIP（Linux Imaging and Printing Object）以前有hpijs, hpoj（hpijs以前是一个单独的项目，但是ghostscript也包含了这个项目。hpoj是针对officejet的。）等开源项目，零散但是有非常有用，其中很多是非官方的，hplip是hpijs和hpoj的整合，受HP官方支持。HPLIP项目包括二进制打印机驱动（HPIJS打印机），以及打印机的维护工具（检查墨水量、清洁和校正打印头，等等）。由于该项目的支持，几乎所有的惠普打印机和一体机（打印/ 扫描/ 复印）都可以正常工作。

CUPS(Common UNIX Printing System，通用Unix打印系统)是Fedora Core3中支持的打印系统，它主要是使用IPP(Internet Printing Protocol)来管理打印工作及队列，但同时也支持"LPD"(Line Printer Daemon)和"SMB"(Server Message Block)以及AppSocket等通信协议。

$sudo apt install hplip cups

b.将用户添加到用户组lpadmin中（这里我的用户为sements）

$sudo usermod -a -G lpadmin sements

c.修改配置文件cupsd.conf

$sudo cp /etc/cups/cupsd.conf /etc/cups/cupsd.conf.bak     #备份
$sudo vim /etc/cups/cupsd.conf

需要修改几处：

Listen localhost:631 修改为 Listen 0.0.0.0:631
在 <Location />， <Location /admin> ，<Location /admin/conf> 三个节点中添加 Allow all

修改后文件如下

sements@beaglebone:/etc/cups$ cat /etc/cups/cupsd.conf

d.重启CUPS服务
