Toner is used in a printer as ink. It is a powder-like substance that is most commonly used in laser printers (as well as photocopy machines). The casing in which the toner is kept is known as a toner cartridge.

Toner used to be made in a simple manner. Carbon and soot accumulated from factories and manufacturing plants were refined and used to fill toner cartridges. This was an efficient method of making toner, but the resulting prints were not as sharp and of a high quality. In an endeavor to improve the quality of the prints, the raw carbon was simply mixed with polymer. The use of polymer in toner was of great help as it was melted by the heat of the fuser and caused it to bind with the fibers of the paper. This produced fine and clear copies of detailed images.

A printer toner cartridge is not an expensive buy. It is reusable printer equipment, and many computer and printing companies across the U.S. offer services to refill them. The cost involved is not too high, and if the refilling process is done through a reputed computer store, such as Hewlett-Packard and Epson, guarantees on the refills are provided.

Printer toner cartridges and the toner itself have seen many technological changes. Earlier, machine toner was transferred from a bottle into a container in the machine. However, modern methods make use of disposable cartridges. Toner cartridges are designed mainly to produce professional quality black text and image printing.
