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.

Famous quotes containing the words line and/or printer:
“The real dividing line between early childhood and middle childhood is not between the fifth year and the sixth year—it is more nearly when children are about seven or eight, moving on toward nine. Building the barrier at six has no psychological basis. It has come about only from the historic-economic-political fact that the age of six is when we provide schools for all.”
—James L. Hymes, Jr. (20th century)
“Although then a printer by trade, he listed himself in this early directory as an antiquarian. When he was asked the reason for this he replied that he always thought every town should have at least one antiquarian, and since none appeared for the post, he volunteered.”
—For the State of Iowa, U.S. public relief program (1935-1943)
