Tips To Understanding Printers Then And Now
Group 1ab
Before the invention of the printer, there were really only 2 ways to pass your stories on to other people. You had to either tell them directly, or write it out for them. Most people couldn’t read, because the art was relatively pointless when text was hard to come by anyways. When printers started appearing in their early forms (as a wax seal) in Egypt and Mesopotamia, they began their march toward the rapid advancements we see today. For Mesopotamians, the cylinder seal was a great way to prove authenticity of important documents, often used to imprint the wax on a sealed envelope. The seals were basically cylinders of stone with raised images on the surface. When rolled across wax or wet clay, it would leave an imprint of what is on that surface or the images. Woodblock printing was used as early as 220 AD by the ancient Egyptian and Chinese populace. Around 1440, Johannes Gutenberg invented the printing press. Widely regarded as one of the most significant inventions in history, Gutenberg based his printing press off the existing technology of screw presses. Soon, books were available to common man, and reading and the printing of text became popular. Scientists, especially, benefited from the invention. Experiments were much easier to pass on and replicate. It wasn’t until the 1960’s that the laser printer and photocopiers began appearing in offices the world over. 9 years behind the Xerox machine, the laser types were invented at Xerox by Gary Starkweather, a Xerox researcher. These are now available at a reasonable price to pretty much everyone, and come in every size from office bulk to tiny home printer. The distant-future sounding 3D printer may play a big part in the future of these devices. Able to create 3D models from digital designs, 3D output devices are already available for a variety of industries. The process of printing something in 3D can take only a few hours. Its results are far more accurate than carving models by hand, and take less time. By adding layers of material instead of removing them, the machines are able to pinpoint dimensions. Before long, 3D printers are projected to become available to the general public. While they had a slow start before the technological boom of the 20th century, the printer has now gained some serious momentum in the technology department. From simple seals to laser output devices to the 3D variety, they’ve definitely come a long way. Rumor has it; they’re working on food printers next.
