我和家人刚刚搬家。除了手机的移动热点外，我们无法访问互联网。这台打印机有拒绝打印的记录，但以前它通常仅花了很长时间即可开始打印（使用 Linux Mint 和有线互联网）。
我现在已经安装了 Ubuntu 20.04 LTS，昨天安装了 hplip (3.22.6)，尽管出现了一些警告和错误，但我还是能够打印测试页。但是，今天我无法让它打印任何东西。我运行了、hp-doctor和hp-upgrade，hp-check尝试将打印机和/或我的电脑连接到我妈妈的手机的移动热点和我自己手机的热点，重新安装了 hplip 并重新启动。它一直拒绝打印，理由是“通信错误”。当打印机连接到她手机的热点时，我妈妈能够使用运行 Windows 10 的笔记本电脑进行打印。
hp-doctor抱怨无法连接到 HPLIP 站点（代码 8），警告无法读取我打印机的打印机和传真机的 ppd 文件，并抱怨无法与它们通信（代码 12）。我不知道如何修复这些问题。
如何使我的 HP Officejet 3830 工作？
