答案1
安装包含包的打印机驱动程序：
sudo apt-get install cups-client cups-common cups-core-drivers cups-daemon cups-filters cups-ppdc cups-server-common debconf ghostscript libavahi-client3 libavahi-common3 libc-bin libc6 libcups2 libcupscgi1 libcupsimage2 libcupsmime1 libcupsppdc1 libgcc1 libstdc++6 libusb-1.0-0 lsb-base poppler-utils procps
然后打开应用程序system-config-printer-gnome并使用打印机。
