I have a friend who wants to install a printer driver. As I understand it, the printer itself needs to be connected physically for this to work.
He also has a desktop, which is the machine with the printer in question.
For some reason, the guy doesn't want to disconnect the printer from the desktop and temporarily hook it up to the laptop for the driver installation. I can only guess that there's a tangle of cords behind the desktop that he doesn't want to deal with.
So, he's asked me a question that I can't really answer.
He's wondering if he can connect the laptop to the desktop via USB ports on both, and thereby have the printer connected to the laptop "through" the desktop. I have no idea what the answer to this question is because I've never come across that issue before.
As I think about it now, the solution seems pretty simple if he doesn't want to mess with the cables behind the desktop.
If he has another USB cable, he can just disconnect the one in the printer that goes to the desktop and then connect the spare and run it to his laptop.
But I'm still curious about this question of connecting the laptop to the desktop via USB ports. Never heard of that and I would expect that the voltage delivered to the laptop over the USB connection would not be near enough to power the laptop.
