Unlike commonly used printers that require ink or cartridges to print, direct thermal printers print by applying heat to the material. Sometimes the terms “direct thermal” and “thermal transfer” can be confused so let’s go into the differences.
Direct Thermal Printer
A direct thermal printer does not use any ink, ribbon, cartridge, or toner. It applies heat at specific temperatures to a heat-sensitive material (such as a label) to make the printer. The material then reacts to the heat applied and makes the impression. Rollo is a direct thermal printer with virtually maintenance free ownership. It is engineered to print at a whopping speed of 150 mm/second which is one 4×6 shipping label per second. Direct thermal printing is ideal for application that last up to 6 months. However, in normal conditions, the print can easily last up to 12 months.
Rollo offers a simple, ribbon-free, compact design.
Thermal Transfer Printer
Thermal transfer printers do require ribbons made of wax that melt into the material. So you will need to load your labels as well as the ribbon. It is essentially another form of ink.
