打印机HP laserjet pro M15a在18.04上不工作

Question

我想让我的打印机在18.04LTS上工作。

我有一个旧的laserjet 1018和一个新的laserjet pro M15a。两人都没有工作，1018人在12.04TLS下工作。打印机被识别，但作业在“停止”状态下留在队列中。从现在开始，我将只讨论new打印机，这是我问题的重点。

谷歌到处都是，现在我正试着跟踪HPLIP在launchpad.net上的这些指令。

然后：

$ sudo hp-setup -i
...
Using connection type: usb
error: No device selected/specified or that supports this functionality.

我尝试了通常的重新安装，动力循环，清理等，现在我处于死胡同。我甚至换了USB电缆，没什么用。

注意:打印机实际上是自动识别为一个不同的版本，甚至名称也与我的名字不一样。我的版本不在可用驱动程序列表中，但我拥有的是推荐选项。见附图。

谁能给我指明正确的方向？

Answer 1

你做错了什么。通常，HP打印机在GNU/Linux上有很好的支持。

Ubuntu18.04LTS已经有了hplip-gui版本3.17.10。

首先，您需要删除ppa:hplip-isv/ppa，它没有用于仿生的包：

sudo add-apt-repository -r ppa:hplip-isv/ppa
sudo apt-get update 
sudo apt-get install hplip-gui

你的打印机支持HPLIP. - 1018从2.7.10开始，M15a从3.18.4开始.两台打印机都可以使用需要专有驱动插件。

简而言之，您需要运行hp-setup，然后运行hp-plugin。

Answer 2

我下载并运行了文件/命令：

sh hplip-3.19.5.run

从现场：

https://developers.hp.com/hp-linux-imaging-and-printing/gethplip

然后按以下指示执行：

https://developers.hp.com/hp-linux-imaging-and-printing/install/install/index

而且起作用了。

之后，我删除了以下与扫描仪相关的程序，即：

 sudo -H pip2 uninstall pip tesserocr opencv-python PyPDF2 imutils  pypdfocr scikit-image scikit-image 
 sudo apt autoremove python-pip libleptonica-dev  tesseract-ocr libtesseract-dev  tesseract-ocr-all libzbar-dev python-zbar

所以试试吧..。:-)
