Test: Input & Output Devices- 1 - Class 10 MCQ

The correct answer is option B: i and iii.
Explanation:
- A line printer prints an entire line at a time, which means it prints all the characters in a line simultaneously.
- It allows multiple copies to be taken at a time, which means it can print multiple copies of the same line without having to print each copy separately.
- However, a line printer is an impact printer, not a non-impact printer. Impact printers use a mechanism that physically strikes an inked ribbon against the paper to create an image, whereas non-impact printers use methods like heat or lasers to transfer the image onto the paper.
- Lastly, a line printer does not print one character at a time. It prints an entire line, not individual characters.
To summarize, a line printer prints an entire line at a time and allows multiple copies to be taken at once. Therefore, the correct answer is option B: i and iii.

Explanation:
An inkjet printer is a type of printer that uses ink to create images or text on paper. Let's analyze each statement to determine the correct answer.
i) prints an entire line at a time:
This statement is incorrect. Inkjet printers do not print an entire line at a time. Instead, they print one small dot at a time, gradually building up the image or text.
ii) is a non-impact printer:
This statement is correct. Inkjet printers are non-impact printers, meaning they do not physically strike the paper to create the image or text. Instead, they use ink droplets to create the desired output.
iii) allows multiple copies to be taken at a time:
This statement is incorrect. Inkjet printers typically do not have the capability to produce multiple copies at a time. Instead, they are designed for single-sheet printing, and if multiple copies are required, the user would need to manually feed each sheet.
iv) prints one character at a time:
This statement is incorrect. As mentioned earlier, inkjet printers print one small dot at a time, not one character at a time.
Conclusion:
Based on the analysis, the correct answer is option A: i and ii. An inkjet printer prints one dot at a time and is a non-impact printer.

To determine which statements are true about a laser printer, we need to compare it with an inkjet printer and a dot matrix printer.
Comparison between a laser printer and an inkjet printer:
- (i) A laser printer gives a better quality printout compared to an inkjet printer. Laser printers use a toner cartridge and a laser beam to produce high-resolution prints with sharp text and graphics.
- (ii) A laser printer is less expensive than an inkjet printer. Laser printers are generally more expensive upfront, but they have lower operating costs compared to inkjet printers. Inkjet printers require frequent cartridge replacements, which can add up over time.
Comparison between a laser printer and a dot matrix printer:
- (iii) A laser printer is more expensive than a dot matrix printer. Dot matrix printers are typically the cheapest type of printer available, but they have lower print quality and slower printing speed compared to laser printers.
- (iv) A laser printer gives a better quality printout compared to a dot matrix printer. Laser printers produce high-resolution prints with sharp text and graphics, while dot matrix printers use a matrix of pins to strike an inked ribbon, resulting in lower quality prints.
Therefore, the correct answer is d. i, iii, iv, as all of these statements are true about a laser printer.
