Printing technology refers to the method a printer uses to create images on paper. The most common technologies include inkjet printing, laser printing and thermal transfer printing. Inkjet printers work by spraying tiny droplets of ink onto the paper, while laser printers use toner and static electricity to transfer the image to the paper. Thermal transfer printers use a heated print head to transfer the image to the paper via a special ribbon. Each technology has its own strengths and weaknesses and is suitable for different applications.
