我有一台旧的 Epson SX400 打印机。它可以在我的旧 ubuntu 20.04 笔记本电脑上使用。我买了一台新笔记本电脑，操作系统相同，但现在打印机无法使用。它可以作为扫描仪正常使用，但当我尝试打印时，它告诉我打印已完成，但什么也没做。
（驱动程序安装似乎进展顺利，我已经多次重新启动了计算机和打印机）。
我不知道这是否相关，但我在连接 USB 时检查了系统日志，并得到以下内容：

在确保打印机被选为默认打印机后，系统日志显示的内容略有不同，但问题仍然存在。

任何帮助都非常感谢。

由于这是 USB 打印机，序列号很可能已更改。下一行显示序列号，如果您检查当前打印机属性，您会发现序列号不匹配。

只需删除打印机，然后重新添加就可以了。
笔记：您可以清除 hplip，因为它仅适用于 HP 打印机。
