Comparing Computer Printers - Inkjet Versus Laser
Computer printers have come a long way since their humble beginnings as mechanical devices tied into an office machine. They are now a ubiquitous part of every home and business machine. Along the way, though, technology has had a great impact on the role of computer printers. The following information covers some of the basic developments that have taken place.

Computer printers use two general methods for printing: line printing or dot printing. Early computer printers operated very similar to a typical typewriter. A letter-like shaped ink ribbon was stamped over the plain paper with an indented fabric ribbon, left an impression of that letter in the print area. Later models were made using a series of tiny pins to form words from individual dots, which were then marked with a pin head. Dot matrix printers are often confused with dot-matrix printers, which are used in some educational computers. Dot matrices use individual LEDs to produce colors.

A dot matrix printer copes with many different types of text and image data. In this process an image file is fed through the printer in rows. To change the color of the dots, the user just manually changes the color balance of the dye inside the ink jet printer cartridge.

The role of the LED is critical to the dot-matrix printers and to the impact printers overall. how to connect wireless printer to computer The LED is responsible for red, green and blue. By changing the color of each dot, the color of the final document is changed. At first glance, it would seem that the impact printer changes the image on the fly, but that is not the case.

What actually happens is that laser and inkjet printers work together to produce a "stippled" finish. This is a result of the light emitted by the laser draping across the image sensor. The ink jet printers add additional chemicals to the paper to enhance the color; this is done before the print quality is changed. The end result is an excellent print quality that is superior to print quality supplied by home and office printers combined.

Impact and laser computer printers both have their place in the business world. However, the best of the best are those which incorporate both technologies. This means that the user can print using a ribbon printer or a dot matrix printer. He can also use the same type of ink in either system. The end result is a machine that is capable of producing excellent print quality.

IBM Selectric Typewriter - When looking at home computer printers, one cannot overlook the IBM Selectric Typewriter. As previously mentioned, the IBM Selectric Typewriter was released in 1981 and has been the standard font for office and business printers ever since. A typewriter, of course, is a representative of the past - it is often associated with the past. However, if one takes a closer look at these old machines, one may find that some of the features now available on modern printers are found on the Selectric Typewriter.

daisy wheel - If you are looking for a printer with a little bit more character and variety, look no further than the IBM Selectric Typewriter, known affectionately as the daisy wheel. These old lines printers are available in three different models - the 24 inch daisy wheel printer, the twenty two inch daisy wheel and the thirty inch daisy wheel. In fact, one can choose to purchase a daisy wheel printer or any of the other three models from the same manufacturer and save money on purchasing all three together.
