Hey, I am planning to buy OKI Pro 8432 WT and a reseller in India told me about coated and uncoated materials. He was very unclear about it so I searched the internet whether Coated or Uncoated materials are used for White toner printers. But I could not find thing except difference between Coated and uncoated papers. The reseller was talking about coated and uncoated wood and mugs. Please help me find some answers.
