记录：让惠普1020Plus 打印机实现局域网打印

本人计划在飞牛nas中部署打印服务实现局域网打印并尝试反向代理实现远程打印

在局域网内使用任意终端软件或者含终端的程序进行代码部署

在飞牛界面开启SSH功能，使用终端连接飞牛系统并 sudo -i 获取root权限

1、安装 cups ：sudo apt-get install cups -y

2、编辑 CUPS 的配置文件：nano /etc/cups/cupsd.conf

复制下面代码替换cupsd.conf原内容

#
# Configuration file for the CUPS scheduler.  See "man cupsd.conf" for a
# complete description of this file.
#

# Log general information in error_log - change "warn" to "debug"
# for troubleshooting...

PageLogFormat

# Specifies the maximum size of the log files before they are rotated.  The value "0" disables log rotation.
MaxLogSize 0

# Default error policy for printers

Windows系键盘：Ctrl+S – 回车 – Ctrl+X 退出；Mac系键盘Control+S – 回车 – Control+X 退出

3、添加管理员：sudo usermod -a -G lpadmin 用户名 ；这里的用户名是你登录飞牛的用户名，后面登录 cups 账号使用的账号密码就是你的飞牛账号密码

4、安装 hplip 驱动文件：apt-get install hplip

5、重启 cups ：service cups restart

6、设置打印机安装插件：hp-setup -i

6.1 ：输入 0 回车，这是选择链接方式；我们选USB连接，会自动发现连接的打印机

6.2 ：输入 d 回车：（d 是默认从HP官网进行下载，可能会报错；报错就输入 p 然后输入文件路径）

需要在这个网站 https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/ 下载三个文件，
在飞牛中新建一个hp文件夹用于保存下载的三个文件
右键查看hp文件夹路径如：/vol1/1000/hp、/vol2/1000/hp等格式
在6.2步骤中输入p后输入hp文件夹路径

7、重启 cups：service cups restart

8、打开 cups 网站：https://飞牛地址:631/admin

点击 Find New Printers
选择 HP LaserJet 1020 (HP LaserJet 1020 USB JL36LZB HPLIP)
必须勾选 Share This Printer 才可以在局域网内找到打印机，勾选后点击Continue
- 在Make选择 HP 点击 Add Printer
- 在Model下滑选框找到驱动文件，名字如：HP LaserJet 1020, hpcups 3.22.10, requires proprietary plugin (en) 随便选一个驱动后点击Add Printer
点击Set Printer Options，设置打印纸
- General-Media Size：选择 A4 210x297mm
- General-：默认 off
- 点击 Set Default Options 完成
