The paragraph describes the process of printing a document using an inkjet printer. Complete the paragraph using the most appropriate terms from the list. Not all of the terms in the list need to be used. • binary • buffer • drum • information • interrupt • laser • liquid • nozzles • operating system • powder • thermal bubble • toner Data is sent from the computer to the printer. The data is held in a print that is temporary storage until the data is processed to be printed. Inkjet printers operate by having a print head that moves side to side across the page. These spray ink droplets onto the page. These ink droplets can be created using piezoelectric or technology. If the paper jams in the printing process, the printing stops and an is sent to the computer.
