Producing hard copies from the computers relies on the use of printer. This implies that the absence of printers would have reduced the importance of computers in the world…
This research paper will discuss the importance of microcontrollers through discussing its association to the various printers’ mechanisms. Introduction The invention of printer was important to the world especially at a time when there was pressing need to produce hardcopies. This need arose because of the invention of computers which required that an individual obtains a printout of the softcopy. Consequently, this led to the invention of the first printer, called a teletype machine but this were inefficient triggering the invention of dot matrix printers making use of microcontroller (Andrews, 45). Intuitively, it is true to say that microcontrollers saved the world in making the nowadays existing printers, inkjet and LaserJet printers. It is important to analyze of how the microcontroller leads to the efficiency of inkjet considering that this type of printer makes use of ink dots. Just like in other devices, like dishwasher, the microcontroller helps in providing motion to the ink dots required to reach the paper and yield images. The action of microcontroller in controlling various processes such as electric current, performance and electric current makes it useful within the printers. This is like saying that the use of microcontroller reflects the quality of output from the printers. ...
This always involves making use of thermal heat to initiate kinetic energy to the drop allowing it to move to the paper. The following is an image showing the impact of heat on the ink drop: As it is shown in the image, the required squirt of ink to the paper occurs after heating the ink which then starts to move in form of a bubble. However, the bubble bursts when it reaches out in the high pressure zone. This pressure causes the ink to burst causing it to hit the paper. The need for cooling effect sets in, at this point, where there is need for the bubble to collapse. The cooling effect triggers the elements in the bubble to cool thereby causing it to collapse. Consequently, the firing process forms a significant stage in delivering a desirable output from the printer. The whole idea of the heating and cooling relies on the need for operating in shorter and longer loops. In turn, the firing process depends on the presence of the microcontroller, which is an embedded system, allowing the manufacturers to use it within the system. In this case, the microcontroller helps in controlling the temperature required for heating and cooling. The ability of the microcontroller to regulate the temperature of the system makes through its CPU allows it to be effective in the printer. The Random Access Memory allows the user to initiate the process of heating and cooling as a temporary process (Ibrahim, 26). Since it stores the data temporarily, it allows the whole process to stop once, the power goes off. This allows the printer to initiate the heating and cooling process, once the power is put on, while also stopping the process when the power goes off. The microcontroller allows the printer to work in longer and closer ...

It acts as the “parent board”, which takes the shape of a printed circuit with connectors for memory modules, expansion cards, optical drives, video cards, sound cards and the processor among others. The motherboard is usually mounted inside a casing just opposite the most easily accessible side.
DIY DIY is an abbreviation for “Do It Yourself”. It is a term that describes building; modifying, repairing or creating something without the aid of professional help. It refers to self-help and building objects of convenience using daily life objects and hardware that is easily available in the market.
For instance, one internal control of security is that the files with important documents are locked inside of the file cabinet (“Understanding Internal Controls”, 2009). This is a strong control measure because it ensures that no one who does not have access to the key of the file cabinet will have access to the files inside.
An interconnection of computers and computing resources that the receptionist, dental assistants and dentists can use from all the offices is required. We are required to design a personal area and local area networks e.g. wireless within an office and using cables .We should also use the metropolitan area network to design an interconnection for all the offices.
However, a lot of time has been taken involving different sequential, impediments use of technology in getting the best, faster and latest printout (How stuff works, 2013). The computer printer which is available in almost every homestead has taken engineer and designers almost a century to adjust availability to all the potential users who may need them for the daily production of documents (How stuff works, 2013).
Permission software are the most helpful infrastructure to help the fashion-ware company control the operations of the satellite branches at different times of the 24 hours in a day and still share the same resources at the central server at the head office.
Due to financial instability, the family could not afford sending Benjamin to school and opted to make him an apprentice to his brother’s employment as a printer. Unfortunate travails with his brother in the printing shop provided the
