Thermal Printer vs Inkjet Printer
Summary: Difference Between Thermal Printer and Inkjet Printer is that thermal printer generates images by pushing electrically heated pins against heat-sensitive paper. Basic thermal printers are inexpensive, but the print quality is low and the images tend to fade over time. While ink-jet printer is a type of non-impact printer that forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper.
A thermal printer generates images by pushing electrically heated pins against heat-sensitive paper. Basic thermal printers are inexpensive, but the print quality is low and the images tend to fade over time. Self-service gas pumps often print gas receipts using a built-in lower-quality thermal printer. Many point-of-sale terminals in retail and grocery stores also print purchase receipts on thermal paper.
Some thermal printers have high print quality and can print at much faster rates than ink-jet and laser printers. A dye-sublimation printer, sometimes called a digital photo printer, uses heat to transfer colored dye to specially coated paper. Professional applications requiring high image quality, such as photography studios, medical labs, and security identification systems, use dye-sublimation printers. These high-end printers cost thousands of dollars and print images in a wide range of sizes.
Dye-sublimation printers for the home or small business user, by contrast, typically print images in only one or two sizes and are much slower than their professional counterparts. These lower-end dye-sublimation printers are comparable in cost to a photo printer based on ink-jet technology.
An ink-jet printer is a type of non-impact printer that forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper. Ink-jet printers have become a popular type of color printer for use in the home. Ink-jet printers produce text and graphics in both black-and-white and color on a variety of paper types. A reasonable quality ink-jet printer costs less than $100.
As with many other input and output devices, one factor that determines the quality of an ink-jet printer is its resolution. Printer resolution is measured by the number of dots per inch (dpi) a printer can print. Most ink-jet printers can print from 1200 to 4800 dpi. The speed of an ink-jet printer is measured by the number of pages per minute (ppm) it can print. Most ink-jet printers print from 12 to 36 ppm. Graphics and colors print at a slower rate.
The print head mechanism in an ink-jet printer contains ink-filled cartridges. Each cartridge has fifty to several hundred small ink holes, or nozzles. The ink propels through any combination of the nozzles to form a character or image on the paper. When the ink cartridge runs out of ink, you simply replace the cartridge. Most ink-jet printers use two or more ink cartridges: one containing black ink and the other(s) containing colors. Consider the number of ink cartridges a printer requires, along with the cost of the cartridges, when purchasing a printer. To reduce the expense of purchasing cartridges, some users opt to purchase refilled cartridges or have empty cartridges refilled by a third party vendor.
