Barcode printers and Label printers come in two kinds of printing technologies Direct Thermal and
Thermal Transfer. Both have their pros and cons and are suitable for different situations. Below is
a rundown on the best and worst of both.
Direct Thermal
Direct Thermal printers work by using the heat of the print head to cause a reaction in the coating of
the label paper. Basically the printer burns a barcode or a logo onto the label. This direct process
does not need a ribbon which saves you money, but it can only print on special labels made for direct thermal printers.
The downside to this type of printing is that labels will
not last a long time. After a period of time the barcode will start to fade and the label will start
to blacken. The labels made with direct thermal printers should not be kept in direct sunlight or exposed
to high temperatures or under constant heavy lights.
The bottom line is direct thermal printing is an inexspensive way to print labels that are
for temporary use. If you need a label to last longer than 6 months you should look into purchasing a thermal transfer printer.
Thermal Transfer
Thermal transfer printing produces crisp images onto labels. Heat is still used in this process except the
heat does not come in contact with the label. Instead the hot print head causes the resin of a ribbon to
form a high quality image on a label. The downside is you have to spend money on ribbons, the upside is you get
higher quality print images and more durability. You can also print on many more kinds of paper.
