安裝一台usb的印表機
[root@linux ~]# mkdir -p /dev/usb
[root@linux ~]# mknod /dev/usb/lp0 c 180 0
[root@linux ~]# chown root:lp /dev/usb/lp0
[root@linux ~]# chmod 660 /dev/usb/lp0
[root@linux ~]# ls -l /dev/usb/lp0
crw-rw---- 1 root lp 180, 0 Nov 7 16:03 /dev/usb/lp0
[root@linux ~]# echo "testing" > /dev/usb/lp0
echo "testing" > /dev/usb/lp0

這段的意思是testing對吧？
但我的印表機依然毫無反應
後來想是不是驅動的關係就繼續探討下去 安裝了cups來設定印表機
當我下達了
lpadmin -p EPSON -v /dev/usb/lp0 -m /usr/share/cups/model/stp-escp2-1290.5.0.ppd -E
出現此錯誤訊息
lpadmin: File device URIs have been disabled! To enable, see the FileDevice directive in "/etc/cups/cupsd.conf".
可是我不知要怎設定cupsd.conf。
可以確定的是cups已經啟動了，網頁也能連上。
到error.log裡看是下行的錯誤訊息
CUPS-Add-Modify-Printer: Unauthorized
可以確定usb裝置是有被捉到的，如下

也確定印表機跟電腦連接應是ok的

但...就是驅動不了
有人可以救救我嗎？
