linux 卸载打印机驱动

要卸载Linux下的打印机驱动，需要先查看当前已安装的打印机驱动，根据驱动的类型进行卸载操作。1、首先使用lsusb查看当前系统上可用的USB设备，lsusb返回的信息中包含了打印机驱动的相关信息：

[root@localhost]# lsusb

Bus 003 Device 005: ID 046d:c077 Logitech, Inc. M90/M100 Optical Mouse

Bus 003 Device 003: ID 03f0:5a07 HP, Inc LaserJet 1217

lsusb的结果表明，存在一个HP的 LaserJet 1217的打印机设备；

2、使用hp-setup -i安装打印机驱动：

[root@localhost]# hp-setup -i

4、如果想更深入地查看已安装的打印机驱动，也可以使用lpinfo查看：

[root@localhost]# lpinfo -v

Direct-USB:/dev/usb/lp0 HP LaserJet 1217

network lpd://192.168.0.1 HP LaserJet 4100

lpinfo查看到的结果就是已经安装的打印机驱动，可以根据其中的信息定位打印机，然后用hp-setup -r来卸载它。

总的来说，要卸载Linux下的打印机驱动，需要先查看当前已安装的打印机驱动，然后用hp-setup -r来卸载它。此外，还可以使用lpinfo查看当前安装的打印机驱动，便于定位要卸载的设备。
