1他宛、首先報錯
cups client error document format not supported
谷歌了嘗試了一大堆解決方法沒有用。
嘗試從local:6300配置也無果元暴。
大部分回答建議修改 .conf文件。
或者reinstall cups or restart cups.
后來看到https://bbs.archlinux.org/viewtopic.php?id=108145建議說
I also had to install foomatic-filters & ghostscript too ....
The printer is perfect now.
I am going to be writing a noobies how to for Arch & Openbox soon ......
于是安裝這兩個包：
sudo apt-get install foomatic-filters
sudo apt-get install ghostscript
得整以，連添加打印機(jī)都添加不了凫乖，又出現(xiàn)新錯誤：
'server-error-internal-error'
連http://localhost:631都打不開了
猜測新安裝的包損壞了原有的CUPS。
重新安裝CUPS吟宦，成功＠航唷！
2殃姓、總結(jié)：
sudo apt-get install foomatic-filters
sudo apt-get install ghostscript
sudo apt-get install cups --reinstall
sudo service cups restart
sudo /etc/init.d/cups restart
