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