我的操作系统是 Debian 11，我的打印机是 HP LaserJet Pro MFP M28a。使用该软件包第一次安装后hplip，打印和扫描都工作正常，但由于某种原因，我不得不重新安装打印机，然后扫描仪根本无法访问XSane。
我尝试了多种选项，但在尝试启动 XSane 时收到错误消息代码 9（“错误：SANE：设备 I/O 期间出错”）或 10（“错误：SANE：内存不足（代码 = 10）”） 。这实际上是 XSane 的错误还是我计算机上的整个配置的错误？
顺便说一句，这是 hp-check 的输出：

我知道有一些警告告诉我 Debian 11 是不支持并且一些必需的包是丢失的（从那时起我就没有删除它们），但我确实做到了为了让扫描仪首先工作，所以必须有一种方法让它重新运行（不会对包造成太多混乱）。
答案1
第一个可能的解决方法（即不使用 HPLIP 解决方案的全部功能）是使用独立开发的无人驾驶后端，sane-airscan如Debian 11 发行说明的第 2.2.2.2 节。安装同名软件包后，我只需使用 XSane 打开时提供的列表中扫描仪的 eSCL 协议版本即可。
scanimage -L可能是一个有用的命令行，用于检查安装后扫描仪的新特殊版本是否确实可用sane-airscan。
答案2
尝试使用 escl:http://localhost:60001 而不是 escl：http://127.0.0.1:60001。后者现在返回 HTTP 重定向到 http://localhost，escl 后端不处理该重定向。
