Printers have come to be part of the general computer buy package. We use them for school work, documents, faxing, and photo printing. There are two types that are generally found in the printing machine market Inkjet, and Laser printers.
The Inkjet printer does just what the name suggest. The ink form the cartridges "jets" out of tiny holes printing out the photo we requested from our computer. They come in black and white, and are also ready in color. Some are designed to print text only, while others consist of photo processing.
Laser printers are very tasteless printers today. They were once belief of as slow and too high-priced to buy for home use. The process of the laser printer is very similar to photocopying. It uses static electricity on a drum to lay out the toner on to the paper and then the laser fuses I. By doing this type of processing, the toner is less likely to bleed when it gets wet, unlike the inkjet printer copies.
Printer processes were not all the time so simple, with the potential results we have today. Before printer devices the computer would generate a "hardcopy" by default. While the computer worked, all data was printed on a paper terminal or by a impact printer, including all the commands that were made on the computer. This provided a lot of constant noise and a lot of wasted paper.
When video display came out, the process improved a little. Users were able to print just what they wanted with out the command codes, but once they scrolled up all data was lost and could not be printed.
Some of the early printers used dot matrix and were attached to the law with serial or parallel cords versus the Ethernet cords and Usb cords we use today that contribute "lightning speed". These cables were also very large and bulky to work with.
There are any large producers of printers today such as Hewlett-Packard, Xerox, Lexmark, and Epson. Prices range anywhere from to any thousand dollars depending on capacity, resolution, and extra features. Many of you have one of these business products in your home today. Never underestimate the power of technology, who knows what we will be doing next.
