Firstly you would need to make sure your mugs are toner-receptive. Please contact us if you need advice on where to purchase. If you would like to print full colour images/logos onto your mug then you would need the Multi-trans printed with an Oki white toner printer. If you would like to print silver or gold you would need the Multi-trans Metallic printed with either your Oki White toner or most Toner Laser printers.
