Toner is used in laser printers and photocopiers.
No, a printing press uses ink, not toner. Toner is typically used in laser printers and photocopiers, where it is fused onto the paper using heat. Printing presses apply ink to paper through various techniques such as offset lithography.
Photocopiers use static electric forces to attract toner particles to the charged drum surface. The charged drum transfers the toner onto the paper, creating a copy of the original image. This process is enabled by the static electricity's ability to create a strong attraction between the charged drum and the toner particles.
Toner is a powder used in laser printers and photocopiers to form the text and images on the printed paper. In its early form it was simply carbon powder. Then, to improve the quality of the printout the carbon was blended with a polymer.
There are many places where one can sell used photocopiers that still work online. There are companies, such as "brkassociates" and "copexinc", that will buy used photocopiers.
Corona wires are thin wires that carry electricity and are used in photocopiers and printers to create a static electrical field. This field helps transfer the toner from the cartridge onto the paper by attracting the toner particles. The corona wires are negatively charged to attract the positively charged toner particles for printing.
Photocopiers make color copies through a process similar to static electricity. The drum inside the copier can be selectively charged so that only parts of it attract toner and therefore chooses specific colors to print.
what is powdery ink
Carbon paper was widely used.

A toner based printer, also called a laser printer in some cases was first used in offices around 1981, but it was invented as early as 1969 by a Xerox researcher named Gary Starkweather.
It is generally recommended to apply toner first, followed by emulsion. Toner helps to balance the skin's pH levels, while emulsion provides hydration and additional skincare benefits. Applying toner first allows the subsequent products to be more effectively absorbed into the skin.
