Which printer forms images with out striking paper?

Answer 1

Printers that form images without physically striking the paper are known as non-impact printers. Unlike older impact printers (such as dot-matrix models) that use mechanical pins or hammers to smash an ink ribbon against the page, non-impact printers use advanced thermal, chemical, or electrostatic technologies to transfer text and graphics. Because they lack heavy mechanical striking mechanisms, they operate quietly, print at much higher speeds, and produce superior image resolution.

The two dominant categories of non-impact printers found in homes and offices today are inkjet and laser printers.

1. Inkjet Printers

Inkjet printers form images by precisely spraying liquid ink onto the page. The core component is the print head, which contains thousands of microscopic nozzles. As the paper passes underneath, the printer uses one of two methods to eject ink:

Thermal Inkjet: Small resistors create rapid heat, vaporizing a tiny bubble of ink that expands and forces a droplet out of the nozzle.

Piezoelectric Inkjet: An electric current causes a tiny crystal to change shape and vibrate, acting as a miniature pump that squeezes the ink droplet out.

Because the droplets are incredibly small—measured in picoliters—inkjet printers excel at mixing colors seamlessly, making them the standard choice for printing high-quality color photographs.

2. Laser Printers

Laser printers rely on static electricity, light, and heat rather than liquid ink. They utilize a fine powder called toner and a rotating cylindrical component known as a photoreceptor drum. The process follows a highly synchronized sequence:

Charging: A roller gives the drum a uniform negative electrical charge.

Exposing: A laser beam draws the digital image onto the drum, neutralizing the negative charge wherever it strikes and creating an invisible "electrostatic image."

Developing: Negatively charged toner powder is applied to the drum, sticking only to the areas neutralized by the laser.

Transferring: The paper is given a strong charge to pull the toner off the drum and onto the page.

Fusing: Heated rollers melt and bond the plastic-based toner permanently into the paper fibers.

Other Notable Types

Beyond these two giants, thermal printers (commonly used for store receipts and shipping labels) use heat to activate color-changing pigments on specially treated paper, while dye-sublimation printers vaporize solid dye onto a plastic film to create professional-grade, smudge-proof photos.

Answer 2

A printer that forms images without striking the paper is a non-impact printer, most commonly a laser printer. It uses a laser beam and toner powder to create text and images electrostatically on a drum, which is then transferred and fused onto the paper using heat and pressure—so there is no physical striking involved. Inkjet printers also fall into the non-impact category because they spray tiny droplets of ink onto the paper rather than hitting it mechanically.

Answer 3

Printers that form images without physically striking the paper are called non-impact printers.

Examples:

Inkjet printers – spray tiny droplets of ink onto paper.

Laser printers – use a laser and toner to create images.

Thermal printers – heat-sensitive paper changes color to form the image.
