Introduction:
In this question, we are asked to identify the characteristics of a laser printer. We need to choose the correct options from the given choices.
Characteristics of a laser printer:
A laser printer is a type of printer that uses laser technology to produce high-quality prints. Let's analyze each statement given in the question and determine its accuracy:
1. Prints an entire line at a time:
- This statement is true. Laser printers use a process called "electrophotography" or "xerography" to print an entire line at a time. This process involves the use of a laser beam to create an electrostatic image of the entire line on a photosensitive drum.
- Correct
2. Non-impact printer:
- This statement is true. Laser printers are non-impact printers, which means they do not require direct contact between the print head and the paper to create an image. Instead, they use a laser beam to transfer toner onto the paper.
- Correct
3. Allows multiple copies to be taken at a time:
- This statement is false. Laser printers generally do not allow multiple copies to be taken at a time. However, some advanced laser printers may have features like duplex printing or collating, which can produce multiple copies in a single print job.
- Incorrect
4. Prints one character at a time:
- This statement is false. Laser printers do not print one character at a time. As mentioned earlier, they print an entire line at a time using a laser beam and electrostatic imaging.
- Incorrect
Conclusion:
Based on the analysis, we can conclude that the correct characteristics of a laser printer are:
- Prints an entire line at a time
- Non-impact printer
Therefore, the correct answer is (A) i and ii.

Explanation:

Laser Printer Characteristics:

- Prints an entire line at a time: Laser printers use a laser beam to scan across the entire width of a page, printing one line at a time. This allows for faster printing speeds compared to printers that print one character at a time.

- Non-impact printer: Laser printers are classified as non-impact printers because they do not physically strike the paper. Instead, they use toner powder and heat to create an image on the paper.

- Allows multiple copies to be taken at a time: Laser printers have the capability to produce multiple copies of a document in one print job. This is useful for printing multiple copies of the same document efficiently.

- Prints one character at a time: Laser printers do not print one character at a time. Instead, they print an entire line at a time, making them faster and more efficient for printing documents.

Therefore, the correct answer is option 'A' as laser printers print an entire line at a time and are classified as non-impact printers.
