Thermal printers are favored by businesses because they are fast, cheap, quiet, and can print in color using wax based "solid ink" or individual colored thermal ribbon cartridges, with a wide spectrum of colors.
1). Choose the right type of thermal paper, preferably one recommended by the manufacturer of your thermal printer, to ensure that the color prints coming out of your thermal printer meet a high specification, and purchase a printer designed for thermal printing. Feed the thermal paper correctly into the thermal printer, and store paper properly, away from sources of heat and moisture, ideally in a manila envelope.
