Orange PI 安装 CUPS 提供打印服务

尘缘linux

使用 orangepizero3 做为打印服务开发板，集成到打印盒子中，用于适配不同的打印设备。

orangepi zero3 2GB 版本安装 Ubuntu 6.1内核版本的镜像
http://www.orangepi.cn/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-Zero-3.html

apt remove docker-ce -y
apt remove dnsmasq -y

rm -f /etc/apt/sources.list.d/docker.list

apt update
apt install libcupsimage2 libcupsimage2-dev libcups2 libcups2-dev -y
apt install cups -y

systemctl enable cups
systemctl start cups

安装好 CUPS 以后，进行 CUPS 配置，包括添加打印机，配置 PPD 文件。

其中，CUPS 如果要提供给其它机器访问，则需要设置为 `shared`。
