问题:
打印机不再显示在设置->设备GUI菜单中,而是出现" Sorry! the system printing service doesn't seem to be available."
以下终端命令输出:
john@john-max:~$ sudo service cups restart
john@john-max:~$ systemctl status cups

我遇到了同样的问题,配置文件的位置不正确,
有一个默认配置文件应该安装在/usr/share/cups/cupsd.conf.default
中,所以我运行:
sudo cp /usr/share/cups/cupsd.conf.default /etc/cups/cupsd.conf
sudo service cups restart
