如何让Canon MX420打印机工作？
我正在使用佳能MX420打印机，直到我将ubuntu升级到11.10。 之后，我可以将它添加到我的打印机，但我无法打印或扫描任何页面！ 我现在应该怎么做 ？
sudo apt-get install cnijfilter-mx420series

配置打印机，您可以使用lpadmin
-
键入以重新启动CUPS守护程序
sudo /etc/init.d/cups restart或sudo service cups restart
-
通过键入将打印机注册到假脱机程序
for usb = / usr / sbin / lpadmin -p [printer_name] -m [PPD_filename] -v cnijusb：/ [USB_port] -E

sudo / usr / sbin / lpadmin -p MX420USB -m canonmx420.ppd -v cnijusb：/ dev / usb / lp0 -E

/ usr / sbin / lpadmin -p [printer_name] -m [PPD_filename] -v cnijnet：/ [MAC_address] -E
sudo / usr / sbin / lpadmin -p MX420LAN -m canonmx420.ppd -v cnijnet：/ 00-00-85-AB-C1-23 -E
3.设置默认打印机
/ usr / sbin / lpadmin -d [printer_name]之类的
sudo / usr / sbin / lpadmin -d MX420USB
4.通过键入来清除usblp模块
sudo nano /etc/modprobe.d/blacklist-cups-usblp.conf使用“blacklist usblp”在行前添加＃ – 注意这可能会导致从CUPS管理这些打印机的同一系统运行多台打印机的问题直
5.键入以检查打印机状态

如果没有错误，那么你的打印机就准备好…….如果错误，我们可以解决它…
