I use the same parallel port for printing on a printer and networking with my laptop without big problems. It takes less than one second to switch from printing to networking. I just add a cheap manual switch between the parallel port, the printer and the laptop. The cable between the switch and the desktop computer is a fully connected one. The switch is just the one used to shared printers when no network is available. It works. [Code: Ansible] [Code: Linux] .:: gamebaidoithuong79-org.netlify.app ::.
Sometimes, the kernel is not very happy because it can't finish its network job. In that case, I shut down the plip interface and restart it when needed. .:: de.enrollbusiness.com ::. .:: telegra.ph ::.
I bought a new parallel card last year but it is still in its box. I'll write an "install a second parallel port" when I succeed in opening the box and add that beautiful card in the last connector I have left. .:: www.arc.agric.za ::. .:: telegra.ph ::.
