Xsane -启动扫描器失败-无效参数
Xsane -启动扫描器失败-无效参数
提问于 2021-08-22 17:38:06
当我试图使用Xsane进行扫描时，会收到一条错误消息：“启动扫描程序失败:无效参数”。
我在以太网上有一个HP激光喷射MFP M227fdn，打印OK。我在Intel Xeon CPU E5-2670 0@ 2.60GHz×16上运行Ubuntu 20.04.3 LTS。当我启动Xsane时，它会搜索扫描仪并看到三个设备：
escl:http//192.168.4.68:8080
hpaio:HP_Laserjet_MFP_M227-M231?zc=NPIF3C167
hpaio:HP_Laserjet_MFP_M227-M231?ip=192.168.4.68CHoosing中的任何一种hpaio设备都会导致“设备I/O期间的错误”，选择escl设备允许Xsane启动，但当我按下“扫描”按钮生成无效的参数错误时会失败。
我已经卸载了Xsane，完成了sudo apt更新& sudo apt升级，通过Ubuntu软件中心重新安装了xsane

-rw-r----- 1 root lp 12270 Aug 18 11:20 HP_Laserjet.ppd.O我可以看到有一些问题，但我不知道如何进行。对.ppd文件的权限似乎是解决此问题的问题之一，但这似乎并不能解决这个问题。提前感谢您的协助。

我能够使用这条线上的几个答案中的步骤来解决这个问题。
简单的回答是:修复Python，以便HPlip可以找到Python3。卸载hplip然后按照下载和编译hplip的说明，它将要求您安装hplip-3.20.6-plugin.run，但是shell脚本在此时发出咳嗽声。我需要找到这个插件这里的适当版本，并通过sudo hplip-3.20.6-plugin.run手动安装它。
长话短说：
从hplip的发射台网站上，我找到了一个对我有用的解决方案。它是这个线程中的post #7。我在问题中描述的问题是由于Ubuntu20.04使用python3而减少了对python2的支持。如果/usr/bin/python链接到python 2版本，那么运行hplip-3.20.**..run将遇到报告的问题，试图安装必要的python组件但失败。要诊断这个问题，运行python -如果您得到一个带有前导数字2的版本，那么修复如下: sudo /usr/bin/python -s /usr/bin/python3..* /usr/bin/python，其中python 3.*是您安装的python3的任何版本。您可以通过运行ls /usr/bin/python*找到这一点。
然后
尝试如下:下载文件到~/Dowloads https://sourceforge.net/projects/hplip/files/hplip/3.20.6/hplip-3.20.6.run/download?use_mirror=nchc，打开一个终端，并删除以前安装的版本: sudo apt删除hplip* Cd到下载安装程序的位置。运行以下命令:shhplip-3.20.6.运行选择安装模式自动，输入一个确保安装程序检测到正确的Linux发行版。输入根用户/超级用户密码。安装程序现在将检测您的系统在安装HPLIP之前需要安装哪些依赖项，如果您的系统缺少现在下载和安装的任何依赖项。./configure为安装准备HPLIP，并验证您的系统具有HPLIP所需的所有依赖项。然后执行“‘make”。为您的系统编译("builds") HPLIP。“”是实际的安装过程，这个步骤是HPLIP实际安装到您的系统的地方。使用‘hp-设置’配置您的打印机。第一步是选择打印机连接类型。接下来，安装工具将显示检测到的打印机。选择要用于打印机的PPD文件，通常需要选择推荐的PPD文件。单击"AddPrinter“完成打印机安装过程。
最后，在安装插件时会出现咳嗽:下载hplip plugin.run的正确版本到/.hplip/ sudo sh hplip-xxxxx-plugin.run，其中xxxxx是试图下载的版本。
Xsane曾为我做过这一过程后对hpiao设备的扫描。
