Thermal printers give users cost-effective printing solutions, and although these printers are relatively maintenance-free, users need to replace their print heads occasionally. This holds true for printers that rely on direct thermal printing as well as those that use thermal transfer printing. People looking for thermal print heads have multiple options from which to choose. Turning to shops that sell printers and related supplies is one way to buy a thermal print head, although buyers can find more options when shopping on websites like eBay. In any case, buyers should know how to distinguish between different types of thermal print heads and learn about the top thermal print heads.

The Two Methods of Thermal Printing

The two methods of thermal printing comprise of direct thermal printing and thermal transfer printing. Direct thermal printing involves selectively heating coated thermal paper when it passes over a thermal print head. The heat results in the coating turning black, which produces the desired imagery. Printers that rely on this technology can print black and red colours. These printers rely on the application of heat at different temperatures. Thermal transfer printing, instead of using coated thermal paper, relies on using heat sensitive ribbon. This process involves gluing a melted coat of ribbon onto the desired printing surface, which helps to produce a myriad of colours.

Thermal Print Head Resolutions

Thermal print heads come in different resolutions, where higher resolutions translate into more dots available in the same surface area. Higher resolution print heads, as a result, work better when it comes to printing small fonts, barcodes, and images. In addition, higher resolution also results in better overall quality. A number of thermal printers allow users to replace existing print heads with those of higher resolutions, which does not require motor adjustments or belt replacements. Represented as dots per millimetre or dots per inch, buyers can find thermal print heads that vary in resolution from 11.8 to 24 dpm, or dots per millimetre.

Cleaning the Thermal Print Head

Most thermal print head manufacturers recommend cleaning them periodically, such as at the end of each roll of labels or at the end of each roll of ribbon. Users should wear gloves to carry out the cleaning, as this prevents contamination of the print head. Users can use lint-free cloth, cotton swabs, and cleaning sticks along with a print head cleaner, like ethanol, methanol, or isopropyl alcohol, to clean the print head. In addition, use products like print head cleaning cards and cleaning film. When it comes to thermal transfer printers, users can use thermal ribbons with inbuilt print head cleaners.
