The Difference Between Thermal Label Paper and Thermal Cash Register Paper
Basically, the difference between thermal label paper and thermal Cash Register Paper is the ability to print at higher speeds, which means less ink use and less drying time. In addition, the stability of thermally sensitive paper is better, which means the paper does not jam or curl as easily as paper made of conventional paper.

Bond paper is an alternative to thermal paper
During the late 19th century, bond paper was used for official documents. Today, it is widely used for a variety of uses, from drawings to writing contracts. It's also used to create purchase orders and lease agreements.
The main difference between bond paper and thermal paper is the chemical coating. Thermal paper uses a combination of chemicals and dyes to produce an image. The coating is usually a gloss or matte finish. Some thermal papers are also protected against grease and oil.
The active coat layer is made up of leuco dye crystals and color developers. When heated, the dye crystals react with the color developer to produce an image. Some thermal papers may also be held in a microcapsule.
The base layer is made of starches, alkali salts, and gelatin. It serves as the binding element and allows the heat to move through the paper.
Stabilizers in thermally sensitive paper
Unlike standard bond paper, thermally sensitive paper uses chemicals to protect the printed image. These chemicals are designed to prevent degradation, fading, and discoloration. There are four main types of chemicals used in thermally sensitive paper.
Thermochromic paper uses a combination of organic acids and leuco dyes. The acid reacts with the dye to give a red or yellow color. The colour is retained when the matrix solidifies.
Stabilizers prevent the dyes from reverting to the crystalline form. They also inhibit recrystallization of the developer. In addition, they prevent the polymer from being damaged by heat, UV light, and water. They also act as antioxidants. They may also enhance pozzolanic properties.
Thermally sensitive paper is often exposed to oils and water. Open heat sources can also discolor the thermal paper. Thermochromic paper is used in thermal printers, cash registers, and audit rolls.

Reliability of direct thermal printing
Using direct thermal printing technology produces sharp, high-quality labels. It's also relatively low-maintenance and easy to use. It's perfect for short-term labeling projects, such as receipts and shipping labels.
Thermal printing is also popular for producing text and images. In addition, it is ideal for printing barcodes. The downside to this type of printing is that it is very sensitive to light, heat, and chemicals. Unless you're using specially treated label material, it's possible for your printed materials to fade and tear too quickly.
Direct thermal printing uses heat to create an image on specially treated paper. This type of printing can be used with a variety of desktop printers. It's also less expensive than thermal transfer printing, though it's not ideal for long-term applications.
