When selecting a printer, you need to consider the following criteria........
- A.
Capacity
- B.
Speed
- C.
Colour
- D.
Quality
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
When selecting a printer, it is important to consider various criteria. Capacity refers to the amount of paper that the printer can hold at once, which is crucial for large print jobs. Speed indicates how quickly the printer can produce prints, which is essential for time-sensitive tasks. Colour is important if you require the printer to produce color prints, as not all printers have this capability. Quality refers to the resolution and overall output of the printer, ensuring that the prints are clear and professional-looking. Therefore, considering all of these criteria is necessary to make an informed decision when choosing a printer.Rate this question:

The quality of printing is measured in ...................... (1 or 3 words)
Correct Answer
dpi, dots per inchExplanation
The quality of printing is measured using dpi, which stands for dots per inch. This measurement refers to the number of dots that can be printed in a one-inch line. A higher dpi indicates a higher resolution and better print quality, as more dots can be placed in a given space, resulting in sharper and more detailed prints.Rate this question:

- A.
1384
- B.
1394
- C.
1284
- D.
1294
Correct Answer
C. 1284Explanation
The current standard for parallel printer ports is IEEE 1284. This standard specifies the electrical and signaling characteristics of the parallel interface, allowing for faster data transfer between the printer and the computer. It supports bidirectional communication, allowing the printer to send status information back to the computer. IEEE 1284 also introduced new modes of operation, such as ECP (Enhanced Capabilities Port) and EPP (Enhanced Parallel Port), which further improved the performance and functionality of parallel printer ports.Rate this question:

Which type of print technology do laser printers use?
- A.
Electrostatic spray
- B.
Electrophotographic
- C.
Impact
- D.
Piezoelectric
Correct Answer
B. ElectrophotographicExplanation
Laser printers use electrophotographic print technology. This technology involves a process where an electrostatic image is created on a photosensitive drum using a laser beam. The drum is then coated with toner, which is attracted to the charged areas of the drum. Finally, the toner is transferred onto the paper and fused using heat to create the printed image. This method allows for high-quality and fast printing, making laser printers popular in both home and office environments.Rate this question:

The toner is applied to the latent image on the drum. Which phase of the laser printer process is this?
- A.
Cleaning
- B.
Conditioning
- C.
Writing
- D.
Developing
- E.
Transferring
Correct Answer
D. DevelopingExplanation
The correct answer is developing. In the laser printer process, developing is the phase where toner is applied to the latent image on the drum. This is done to make the image visible and ready for transfer onto the paper.Rate this question:

Daisy-wheel and dot-matix are examples of ............ printers. (1 word)
Correct Answer
impactExplanation
Daisy-wheel and dot-matrix printers are examples of impact printers. These printers work by physically striking an inked ribbon against the paper, creating the desired characters. The impact of the printing mechanism on the ribbon transfers the ink onto the paper, resulting in the printed output. This is in contrast to non-impact printers, such as laser or inkjet printers, which do not involve any physical contact between the printing mechanism and the paper.Rate this question:
- 9.
There are two types of inkjet nozzles. One type is piezoelectric, the other is ................. (1 word)
Correct Answer
thermalExplanation
The correct answer is "thermal". The question states that there are two types of inkjet nozzles, one being piezoelectric. This implies that the other type must be different from piezoelectric, and the only remaining option is "thermal". Therefore, "thermal" is the correct answer to complete the sentence.Rate this question:

Which type of printer melts ink and sprays it through a nozzle onto a drum to transfer an image onto paper?
- A.
Fusion ink
- B.
Impact
- C.
Inkjet
- D.
Laser
- E.
Solid-ink
Correct Answer
E. Solid-inkExplanation
Solid-ink printers melt ink and spray it through a nozzle onto a drum to transfer an image onto paper. This type of printer uses solid blocks of ink that are melted into a liquid form before being sprayed onto the drum. The ink then solidifies on the paper, resulting in vibrant and durable prints. Solid-ink printers are known for their high-quality output and are commonly used in professional printing environments.Rate this question:

It is good practice to plug a printer into a UPS (TRUE or FALSE)
Correct Answer
no, falseExplanation
Plugging a printer into a UPS (Uninterruptible Power Supply) is not considered good practice. UPS devices are typically used to provide backup power to critical devices during power outages or fluctuations. While it may seem logical to protect a printer from power interruptions, printers are not typically considered critical devices that require uninterrupted power. Additionally, UPS devices are generally more expensive than regular surge protectors, which can adequately protect printers from power surges. Therefore, it is not necessary or recommended to plug a printer into a UPS.Rate this question:

..................... is a set of instructions stored on the printer that controls how it operates. (1 word)
Correct Answer
firmwareExplanation
Firmware refers to a set of instructions that are stored on a printer and control its operation. It is a type of software that is permanently installed on the printer's hardware, allowing it to function properly. Firmware can be updated or upgraded to add new features or fix any issues that may arise.Rate this question:

................... data transfer is the movement of multiple bits of information in a single cycle. (1 word)
Correct Answer
parallelExplanation
Parallel data transfer refers to the simultaneous movement of multiple bits of information in a single cycle. This means that multiple bits are transferred at the same time, increasing the overall speed and efficiency of the data transfer process. This is in contrast to serial data transfer, where bits are transferred one after the other. Parallel data transfer is commonly used in computer systems and devices that require high-speed data transmission, such as printers, hard drives, and network connections.Rate this question:

What type of printer has paper with a short shelf life?
Correct Answer
thermalExplanation
Thermal printers use heat to print on special thermal paper, which has a coating that reacts to heat. This type of paper has a short shelf life because over time, the coating can degrade or fade, resulting in poor print quality or complete inability to produce prints. Therefore, thermal printers require fresh thermal paper for optimal printing results.Rate this question:

Which type of printing process uses solid sheets of ink that change directly to gas when the printing head heats the ink?
- A.
Dye-sublimation
- B.
Impact
- C.
Inkjet
- D.
Solid-ink
- E.
Thermal
Correct Answer
A. Dye-sublimationExplanation
Dye-sublimation printing process uses solid sheets of ink that change directly to gas when the printing head heats the ink. This process involves transferring dye onto a medium (such as paper or fabric) using heat. The solid dye particles are converted into gas without going through a liquid phase, resulting in high-quality prints with vibrant colors and sharp details.Rate this question:
