You can _probably_ get away with just unplugging at the printer. The printer
has ’soft power’, which means that there’s always power on inside even
when you hit the ‘off’ button, unless you unplug it. Unplugging from both
ends is something the paranoid do, so that when the power cable is plugged
back in again they _know_ that it’s plugged in firmly, properly, and in the
correct sockets. (You would not _believe_ the number of printer and computer
problems I’ve seen which were caused by wrong cable/port, or not properly
inserted cable, or combination)
If the printer is plugged into a surge protector or a power strip, hitting
the ‘off’ switch there will probably work, too, as long as the cable was
properly inserted in the first place.
