How could I make a printer VIP only

I want to make a printer a vip printer, so only a VIP can buy it.

I use ULX and here is the code:


AddEntity("VIP Bronze Money printer", {
	ent = "vbronze_money_printer",
	model = "models/props_c17/consolebox05a.mdl",
	price = 1000,
	max = 6,
	cmd = "/buyvipbronzeprinter",
})

Thanks!
