I usually don’t bother with installing a printer. I have one, but I rarely use it. Jen however needed to print something, her Windows Dell is broken (another story), so I installed cups and the HP drivers, and connected the printer. I tried to add it via the webinterface, but it wasn’t found.
I modprobed the right module. Nothing. I rebooted, although I knew it wasn’t necessary. Nothing. I reinstalled the drivers, but of course, nothing happened. I muttered a bit, when Jen passed and asked if I had checked the cables.
“Well, of course I did, I just plugged it in, and at the back of the printer it’s…oh. Thanks. And I’m an idiot.”
Printer was up and running a minute later…
