Is it dangerous for the computer to plug/unplug monitor/LPT-printer when it is running?

Is it dangerous for the computer to plug/unplug monitor/LPT-printer when it is running? I remember back in the 90s someone told me it was bad for a computer to plug and unplug a monitor or printer (LPT/parallel) into a computer while it was running.

"Most monitors have separate power connectors today
(which do not connect to the PC power supply)

The power on the data cable is not sufficient to cause significant sparking
The data cable design makes it difficult to 'short' ground and other pins
I have frequently done this with a large number of 'headless' lab machines and never seen a fault

I have a similar feeling for printers, but would like to check others who have more experience with them."

"When I still had parallel ports, I killed some of them every once in a while by hot-plugging a printer. So I cannot recommend that.

I never killed a graphics card or monitor, but of course that doesn't mean that it cannot happen."
