the oldest inkjet technologies in use and is fairly mature. One of its advantages is the very high velocity (~50 m/s) of the ink droplets, which allows the ink drops to be thrown a long distance to the target. Another advantage is freedom from nozzle clogging as the jet is always in use When printing is started, the software application sends the data to be printed to the printer driver which translates the data into a format that the printer can understand and checks to see that the printer is online and available to print. The data is sent by the driver from the computer to the printer via the connection interface. The printer receives the data from the computer. It stores a certain amount of data in a buffer. The buffer can range from 512 KB random access memory (RAM) to 16 MB RAM, depending on the printer model. Buffers are useful because they allow the computer to finish with the printing process quickly, instead of having to wait for the actual page to print. If the inkjet printer has been idle for a period of time, it will normally go through a short cleaning cycle to make sure that the print heads are clean. Once the cleaning cycle is complete, the inkjet printer is ready to begin printing

the rollers, which feed a sheet of paper from the paper tray / feeder into the printer. A small trigger mechanism in the tray / feeder is depressed when there is paper in the tray or feeder. If the trigger is not depressed, the inkjet printer lights up the "Out of Paper" LED and sends an alert to the computer. Once the paper is fed into the inkjet printer and positioned at the start of the page, the print head stepper motor uses the belt to move the print head assembly across the page. The motor pauses for the merest fraction of a second each time that the print head sprays dots of ink on the page and then moves a tiny bit before stopping again. This stepping happens so fast that it seems like a continuous motion. Multiple dots are made at each stop. It sprays the CMYK (cyan / magenta / yellow / black) colors in precise amounts to make any other color imaginable. At the end of each complete pass, the paper feed stepper motor advances the paper a fraction of an inch. Depending on the inkjet printer model, the print head is reset to the beginning side of the page, or, in most cases, simply reverses direction and begins to move back across the page as it prints. This process continues until the page is printed. The time it takes to print a page can vary widely from printer to prir. It will also vary based on the complexity of the page and size of any images on the page.
