There was an error during the CUPS operation: 'client-error-not-possible'.

当参考ubuntu18.04连接windows共享打印机 时有时可能会出现

“There was an error during the CUPS operation: 'client-error-not-possible'.”错误

通过查看 /var/log/cups/error_log日志并查看samba packages 就会发现缺少“samba-client”

解决方法：

sudo apt  install samba-client
systemctl restart cups.service

发现处理linux计算机的问题要善于看log 日志。
