Thermal Paper Rolls are used in thermal printers for customer receipts, tickets, etc. Obviously, there are lots of brands of thermal printers popular, such as Epson, Zebra. For each model of the printer, it has the fixed paper roll size it needed. This makes easy for us to choose paper rolls for our printer.
Paper Roll Size:
The three key factors for roll size are width, diameter and length. The most popular width is 57mm (2 1/4″) and 80mm (3 1/8″), while 60mm, 70mm & 110mm for some other printers. For the diameter, it varies from 30mm to 250mm. Here comes length of roll. In a fixed paper roll size, such as 80x80mm, the lower paper gram mage is, the long meters this roll contains. You can use this roll for longer time.
What is a good thermal paper roll?
Do not say it is just a piece of paper. Paper is crucial to the machines.
For the specific printer, the paper roll size is fixed. So here comes the paper quality. When you get a paper roll at hand, please see the whiteness, smoothness, image sensitivity.
It’s your choice for the whiteness while it does not affect the usage.
For bad quality thermal roll, it is rough and coarse on front and back of paper. It is not lint free, so it leaves powder inside of the printer when you use it. This is harmful to the printer and will reduce the life span of the machine. To protect it, please pay attention to paper smoothness.
Image sensitivity is another important factor. People will find they see the image is clear or fuzzy on receipts from different shops. It does. Thermal Paper is coated with a chemical that is why it changes colors when exposed to heat. If the coated chemial is even and enough, the text showed on paper will be clear, black and crisp. A flame on back of paper for one second can change color of paper. A fingernail swiped quickly across the paper will also change it. This is the same theory. Please make sure the image is even and clear.
