我已经在Leno T470s笔记本上执行了新的/干净的v20.04安装。安装没有问题,所有的位似乎都能工作。很高兴到现在为止。
然而,每次我启动我的笔记本电脑(甚至在工作甚至空闲的时候),我的爱普生WF-7520局域网打印机都会被探测(发现/浏览)。这让我和家人都发疯了,因为探针让打印机的反应就像刚初始化过一样。即使我没有添加打印机,也会发生这种情况。打印机不是“自动”添加的。我已经手动添加了打印机。
我(经过多次搜索)尝试过:
为了完整起见,我列出了一个正在运行的服务列表,以防止它提供任何洞察力,

您的Ubuntu系统不探测网络;这将是一个活动进程。cups-浏览和和avahi-守护进程是被动网络上DNS-SD通信量的发现者。在您的例子中,WF-7520将产生一些(可能全部)这种流量。
因此,从它的web界面上关闭Bonjour和/或IPP on WF-7520,看看您如何继续下去。
