What Makes A Printer Print?
You frequently utilize a printer for your everyday needs, but have you ever considered the nuts and bolts of how printers work? Often, we never consider the everyday technological features of our lives until they break down and then we have no idea how they are supposed to work. It's actually pretty interesting discovering how printers work if you've never looked into the process before.
If you have a printer in your house or small business, it's most likely an inkjet printer. Inkjet printers have been the most popular printers to purchase since their introduction into the marketplace in the late 1980’s. And how do they function? Sometimes when you look at a page printed from an inkjet printer, you'll see just clean, straight lines. Take a closer look. If you put the paper underneath a magnifying glass, you’ll notice that the lines are actually created by very small droplets of ink. The printer sprays tiny droplets of different inks in the proper pattern and mixture onto the paper to make different colors and form the image, even if it's a full photograph or a print in black and white.
The dots of ink are incredibly tiny, with a diameter even thinner than that of a human hair! Almost all inkjet printers come with just a few staple colors. To form the entire color palette, the printer must mix two different colored dots of ink together. For instance it may put blue and red together to make purple, or yellow and blue together to make green.
Inkjet printers and laser printers are entirely different technological beasts. As previously stated, tiny droplets of ink sprayed by the inkjet printer make the pictures appear. Laser printers are slightly different,however, because they use dry ink, also called toner, instead of wet ink. Then, through a combination of static electricity pulses and heat, the ink is bonded to the paper. The dry ink powder is also called laser toner.
If you would take a printer apart, you'd find a piece at the core of its technology called the print head. This head is puntured by tiny nozzles that control the spray and flow of the ink droplets on the paper. The ink cartridge is placed in this area of the printer and, with the aid of a print head stepper motor, quickly whizzes back and forth across the paper.
When you print something off from your printer, you kick off a chain of events. First the data is sent to the printer driver. The driver then translates the data into a language that the printer can understands and makes sure that the printer is ready to print. If there has been a lag time since the last printing job, the printer will need a quick cleaning session. Once it is clean, it will start to pull the paper into the printer. As the ink is sprayed onto the page, the motor stops for the briefest of moments. This process occurs so quickly, though, that the paper appears to move out continuously. This is what happens for the document to be transmitted from bits of data on your screen to a sheet of paper in your hand.
