Printer Overview <ul><li>Printers are a vital part of modern PC systems. </li></ul><ul><li>The need for hard copies of computer and online documents is no less important today than when the paperless revolution began several years ago. </li></ul><ul><li>The most commonly used printers in use today are electrophotographic type laser printers and sprayed inkjet printers. </li></ul><ul><li>Other types include thermal and dye-sublimation printers. </li></ul>
Understanding Dot Matrix Printer Operation <ul><li>The dot matrix printer belongs to a printer class called impact printers. </li></ul><ul><li>With impact printers, the printing part actually impacts a printer tape or inked ribbon to cause characters to be formed on paper. </li></ul><ul><li>In the dot matrix printer, this impact happens as the print head fires pins (or print wires) at an ink ribbon, which contacts the paper and leaves a mark. </li></ul>
Understanding Inkjet Printer Operation <ul><li>Color inkjet printers are the most popular type of home printer. </li></ul><ul><li>Inkjet printers have two kinds of print heads. </li></ul><ul><li>One popular brand of inkjet printers has a type of head called a thermal-shock or bubble-jet print head. </li></ul><ul><li>It has a heating element that surrounds each nozzle and when heated by an electrical current, it causes the ink to expand. </li></ul><ul><li>This expansion causes the ink to be ejected through the nozzle. </li></ul>
Understanding Laser Printer Operation <ul><li>As in photocopiers, static electricity is the primary principle that is used in the operation of a laser printer. </li></ul><ul><li>This is the same static electricity that causes lightning or other oppositely charged particles to attract each other. </li></ul><ul><li>This attraction is used to temporally hold small dry ink particles called toner to a statically charged image on an electrophotographic drum. </li></ul>
Print Capacity and Speed <ul><li>If speed is an important consideration, lower-end inkjet printers are not a good choice. </li></ul><ul><li>Generally inkjet printers will print text at two to six pages per minute. Printing a page of graphics can take several minutes. </li></ul><ul><li>Compare this with color lasers, some of which can print at 16 pages per minute, and send out the first page in about 10 seconds. </li></ul><ul><li>The question to consider in making a decision has to do with speed and cost. </li></ul>
Configuring Individual Printer Options <ul><li>Each model of printer can have its own set of unique user-selectable options. </li></ul><ul><li>The two main categories of printer options are media handling and printer output. </li></ul>
Selecting a Default Printer <ul><li>A default printer is the printer to which all print jobs are sent if another printer is not selected. </li></ul><ul><li>Choosing or changing the default printer on a computer can be done in three ways: </li></ul><ul><ul><li>During printer installation </li></ul></ul><ul><ul><li>Manual selection </li></ul></ul><ul><ul><li>Using the printer queue </li></ul></ul>
