使用打印服务几个月后，我决定尝试在 Manjaro 上设置我的 Epson XP 225 打印机，因为我懒得设置它。我从AUR安装了Epson驱动，安装顺利。通过一些搜索，我设法添加了我的打印机（我通过 USB 使用它，不受 wifi 或蓝牙设置的困扰），并设法使用在线本地主机工具手册来启用我的打印机。我曾经遇到过这些错误：

经过一些小的调整（将 DefaultAuthType 更改为 None 并安装上述驱动程序）后，这是我剩下的唯一错误：

当我尝试打印某些内容时，作业显示“正在处理”，但它没有完成。
lpstat -l 给出：

这非常令人沮丧，这对我来说是一个无用的错误。我也无法找到任何可以解决此最终消息的方法。我希望这里有人能提供帮助，我将不胜感激。
