I don't think it is required but might be convenient.

Likely the machine has a control panel of some sort that includes a disconnect.

Is it hard wired or plug-in?

If it is plug-in then the cord cap will be the local disconnect. If not, then a disconnect switch is more convenient than a breaker lock depending of course on how far the panel is located from the machine.

My thought would be that a printing machine will be a finicky machine and need to be serviced more ofthen than many devices and that a local disconnect would be a good idea for the safety of the person servicing the printing machine.

It is a good idea. But if there is a plug, you just unplug it. You can put a locking cover over the plug cap too if you are worried. Lots of people sell those now.
