我相信我的计算机硬件与这台打印机兼容，但我使用的是 Ubuntu gnome 14.04，而且我不确定它是否兼容。
答案1
对于 HP 和较新的打印机，最好直接从 HP 安装最新的 HPLIP。Ubuntu 存储库中有一个版本的 HPLIP，但它通常较旧，不支持最新的打印机或功能。
您可以直接从 HP 获取 Linux 安装程序脚本。支持大多数 Linux，包括 Ubuntu 及其所有打印机。有关具体支持内容的详细信息，请参阅链接。

运行它时，它会创建大量文件和文件夹。最好将其复制到其自己的文件夹中，而不是留在下载中。
如果您收到无系统托盘错误，您可以这样做。我总是在重新启动后忽略它。无系统托盘错误：从管理菜单中打开“启动应用程序”编辑器。添加一个新程序，命令为：sleep 10;/usr/bin/hp-systray
