The question says " which prints all the A's in a line ".

So as per the definition, the given answer is correct.

A line printer is an impact printer which makes use of a continuous feed of paper and prints one line of text at a time.

LINE PRINTER IS THE RIGHT ANSWER.

The different types of line printers are drum printers and chain printers.

In a typical drum printer design, a fixed font character set is engraved onto the periphery of a number of print wheels, the number matching the number of columns (letters in a line) the printer could print.

All of the hammers fire simultaneously when printing a line that consists of the same character in all columns, such as a complete line of dashes ("----").

What is the correct answer?

Line Printer is not the correct answer. You have copied this question from CoolInterview site but Definition of line printer from wikipedia is below,

"The line printer is an impact printer in which one line of text is printed at a time. They are mostly associated with unit record equipment and the early days of digital computing, but the technology is still in use. Print speeds of 600 lines-per-minute (approximately 10 pages per minute) were achieved in the 1950s, later increasing to as much as 1200 lpm. Line printers print a complete line at a time and have speeds in the range of 150 to 2500 lines per minute. The different types of line printers are drum printers and chain printers".
