USB cable plugged into the socket?

My friend's son plugged the USB data cable from the printer into the power connector (connection for charging via USB) instead of the laptop.

When he then put it in the laptop, it couldn't find the printer.
A connection via LAN cable still works and the printer is still printing.

What happens when you plug the data cable into the power connector?
Could I be lucky that only the cable is defective, or do I have to expect that the USB port on the printer has been "smoked away"?

Nothing should really happen. Charging is usually carried out via the supply lines and not via the data lines

Nothing. The data pins of the charger will probably not have any counterpart on the power supply side. The printer can't be harmed by the 5V voltage from the power supply unit, as it must be designed for it in accordance with the USB specification.

So the printer is not recognized by the PC for another reason.

You can't do more than try…

Uff… Well, it depends. A USB socket sends a current of 5V and a strength of 1A.

If he had an adapter in between, far more than 1A could come to a socket that was only intended for data traffic, which could lead to the fact that he has fried the data socket and it is now unusable.

Nothing happens because both the USB port on the computer and the one on the socket provide a 5V supply voltage.

No, it is not possible that way, as no data lines are connected to the USB port of the charging power pack!

Actually nothing broke! Thank God! 🙏
