Introduction
A printer is an output device that produces text and graphics on paper.
Major types of printer Printers can be divided into two main groups, impact printer and non-impact printer.
Impact printer produces text and images when tiny wire pins on print head strike the ink ribbon by physically contacting the paper.
E.g. Dot matrix printer, Daisy wheel printer.
Non-impact printer produces text and graphics on paper without actually striking the paper.
E.g. Laser printer, Inkjet printer, Thermal printer.
Inkjet Printers
Inkjet Printers Inkjet printers are non-impact printers which print text and images by spraying tiny droplets of liquid ink onto paper. They are the most popular printers for home use.
Currently, most inkjet printers use either thermal inkjet or piezoelectric inkjet technology. Thermal inkjet printer uses heating element to heat liquid ink to form vapor bubble, which forces the ink droplets onto the paper through the nozzle. Most inkjet manufacturers use this technology in consumer inkjet printers.
The inkjet head design is also divided into two main groups: fixed-head and disposable head. Fixed-head is built into the printer and should last for the whole life of the printer. It produces more accurate output than cheap disposable head. The ink cartridges for fixed head printers are also cheaper as the print head does not need to be replaced. However, if the head is damaged, the entire printer has to be replaced.
Disposable head is included in replacement ink cartridge. It is replaced each time an ink cartridge runs out of ink.
Advantages:
1. Low cost.
2. High quality of output, capable of printing fine and smooth details.
3. Capable of printing in vivid color, good for printing pictures.
Disadvantages:
1. Print head is less durable, prone to clogging and damage.
2. Expensive replacement ink cartridges.
3. Not good for high volume
