In our previous article, we explained the three common types of receipt paper used for POS systems. But how can you tell if a paper is thermal? In this article, we’ll introduce three simple methods to identify thermal paper.
1. Scratch the Paper with Your Fingernail
The easiest way to identify thermal paper is to scratch its surface with your fingernail. As mentioned above, thermal paper has a heat-sensitive chemical coating on its surface. When a fingernail scratches the paper surface, friction and pressure generate heat; then the heat activates the coating and leaves a black mark on the paper.
To ensure a reliable result, scratch both sides of the paper and see whether you can see black marks. Most thermal paper is coated on only one side, so a dark mark should appear on the thermal side. If neither side develops a dark mark, the paper is probably not thermal paper.
2. Observe and Feel the Paper Surface
Another way to identify thermal paper is to examine and feel its surface, then compare it with bond paper or carbonless paper. Thermal paper often has a smoother and slightly shinier surface because of its coating.
However, in some cases, some bond paper also has a very smooth surface, so observing and feeling the paper surface isn’t the best way to determine if it is thermal paper.
3. Test the Paper on A Thermal Printer
The most reliable way to identify thermal paper is to test it in a direct thermal printer.
A direct thermal printer uses heat to create text and images on the coated surface of thermal paper instead of using ink, toner, or ribbons. If you load ordinary bond paper or carbonless paper into a direct thermal printer (such as an Epson TM-T88VII), the printer will only feed the paper through, but no image will appear because these papers do not have a heat-sensitive coating. If clear text or images appear when the paper passes through the printer, it is thermal paper—and its coated side is facing the printhead correctly.
Ready to Choose the Right Thermal Receipt Paper?
Thanks to thermal paper, it makes receipt printing fast, convenient, and cost-effective across industries in retail, hospitality, entertainment, and banking. With direct thermal printing, there is no need to purchase or replace ink cartridges, toner, or ribbons. All you need is a compatible thermal printer and the correct paper rolls.

Frequently Asked Questions
1. Can I use thermal paper in my inkjet or laser printer?
No, thermal paper only works for thermal printers. Inkjet and laser printers use regular (bond) paper with ink or toner. If you try to use thermal paper in a regular printer, it won’t generate an image, and it could even jam or damage the printer.
2. What happens if I try to use regular paper in a thermal printer?
If you load regular paper into a thermal printer, you won’t see anything printed on the paper. It’s because thermal printers require specially coated thermal paper to produce text or images. They rely on heat, not ink or toner. You’ll just get a blank piece of paper.
3. Is there any normal A4 paper that feels like thermal paper?
Thermal paper has a unique coated, smooth feel, and most regular A4 paper isn’t the same. Some specialty thin or glossy papers come close, but they aren’t designed for the same use and won’t react to heat from a thermal printer. But please note that A4 thermal paper is available in the market nowadays, they are specifically designed for use on A4 portable thermal printers.
4. Does it matter what thermal paper I get for my thermal printer, or are they all the same?
Not all thermal papers are created equal. Please always check your printer’s specs for size and compatibility, and choose quality-tested rolls for best results. Cheap or mismatched paper can cause jams, fading, or worn-down print heads.
