|Printer Ribbons, commonly used with typewriters, cash registers, and dot matrix printers serve the function of transferring ink to paper, when they come in contact, via heat and pressure. The cloth or polyester Ribbons are coated with a layer of pigmented wax, resin, or a mixture of the two, which will easily melt onto desired surfaces with the use of a temperature controlled printhead. The printhead basically takes the given image and traces that image onto the ribbon itself or drum unit. Either a hammer or roller will create the necessary pressure against the ribbon and paper creating the impact to adhere the ink to the page. The cloth ribbons are used in impact printing with devices such as typewriters, teleprinters, and mechanical calculators, while the thermal polyester ribbons vary in composition to efficiently serve different printing tasks. The wax ribbons are ideal for producing labels but must be kept in a dry location away from chemicals and oils. The Resin ribbons can print on plastic and polymer materials, given that the pigment does not easily dissolve when exposed to water, oil, and chemicals. The Wax and Resin conglomerate produces finely detailed images which can endure a little bit of water.
