Fabulous Fun Facts: Inkjet vs. Laser Printing

Madison Company lives and breathes sensors, so of course we get a kick out of fun facts about sensor applications as well. See if you can guess where a sensor is used after you read this Fantastic Fun Fact! (Pssst…. You’ll find the answer in parentheses below!)

The development of xerography – the ability to make sharp, permanent copies on ordinary paper – is a fascinating read. The process was invented by an unknown patent attorney and was initially turned down by more than 20 different corporations, including IBM, GE and Eastman Kodak. It took more than 20 years to develop the first commercial copier, which weighed 650 pounds!

The development of the laser printer followed, and the word ‘Xerox’ found its way into the English lexicon as the go-to term for making paper copies – as flattering a tribute to the process as one can get.

These days, copiers are ubiquitous, though technologies differ. The two most well-known are inkjet and laser printing. Laser printers are commonly used when medium-quality color images or large quantities of black-and-white and colored documents are needed. An inkjet printer is used when gallery-quality photos are required. Inkjet printers spray ink through microscopic nozzles onto a substrate, which can include different types of art papers to produce a high-end product.

Thanks to LD Products and Smithsonian Magazine for their informative articles on the evolution of copiers and printers.

(But where is the sensor? In inkjet printers, the ink is contained in a vessel that requires a level sensor to keep the ink well full!)
