我最近安装了 Ubuntu 20.04，并且有一台三星 Xpress M2022 打印机。但它似乎不起作用。我从互联网上下载了 ppd 文件，但也没有用。然后我尝试了不同的方法通过在线搜索进行调试，但似乎没有任何效果。我不确定如何找到问题以及如何找到此错误日志。
这样做sudo journalctl -b 0 -u cups会给我这个输出：

奇怪的是，尽管我的打印机是三星的，但它与 HP 有关系。

答案1
我没有 M2022，但我有 M2070W，我认为您应该能够使用从 HP 支持网站下载的官方安装程序 V1.00.39_01:17（HP - 这不是错误）。您应该尝试下载并解压 tar.gz 文件，进入解压后的目录并运行 install.sh（我不知道这是否有必要，但我以 root 用户身份执行了此操作）。然后我转到 CUPS localhost:631，删除自动安装的打印机，然后使用列表中的第一个驱动程序再次添加它。我可以通过 USB 和无线以及扫描仪添加它。如果您尝试这种方式，请写下它是否适合您。顺便说一句，我认为三星的打印机部门在此期间被 HP 收购，现在您应该使用 HP 网站上的 Ubuntu 驱动程序。
答案2
该打印机的 URI 已指定为
usb://Samsung/M2020%20Series?serial=ZFCDB8GG3D0006B
用户在系统上的某个位置有一个 PPD，该 PPD 已被指示为正确的 PPD。PPD 的位置未知（但如果有必要，我们可以找到它）。rastertospl 过滤器也在系统上。此命令设置打印队列：
lpadmin -p 2022 -v URI -E -P /路径/到.PPD
代替为了URI然后用
lp -d 2022 /etc/nsswitch.conf
