DarkRP Money Printers not working? At all?

Whenever I try to spawn a money printer, it doesn’t work. It just says “/buyprinter” in the chat, like it can’t read the entity files. It’s the printer from the wiki. I put it into DarkRP/entities/entities and called the folder “money_printer”.
Here’s the code in DarkRP/gamemode/addentities.lua:

AddEntity("Money Printer", {
	ent = "money_printer",
	model = "models/props_c17/consolebox01a.mdl",
	price = 1000,
	max = 3,
	cmd = "/buyprinter"

But it doesn’t work.

I think it needs to be changed to “/buymoneyprinter”
