What's the Difference Between a Printer Toner & a Drum?

Printer Drum.
The drum in a laser printer is the central component. It's the device that receives the image from the laser and transfers it to the paper to produce the final print. Photocopiers also contain drums that work in much the same way. The difference between laser printers and copiers is how the image is transcribed onto the drum.

The printer drum is also known as a photoconductor by a few print accessory manufacturing companies such as Lexmark, Epson and Ricoh. Others refer to it as a drum cartridge, photoconductor kit, or photoconductor unit.

Printer Toner
Toner is a powder used in laser printers and photocopiers to form the printed text and images on the paper. In its early form it was simply carbon powder. Then, to improve the quality of the printout, the carbon was melt-mixed with a polymer. Toner particles are melted by the heat of the fuser and bind to the paper.

In earlier machines, this low-cost carbon toner was poured by the user from a bottle into a reservoir in the machine. Current machines feed directly from a sealed laser toner cartridge.

Modern laser toner cartridges, intended for use in color copiers and printers, come in cyan, magenta, yellow and black
