The computer device primarily used to provide hard copy is the _______________.
The correct option is B Line Printer
The computer device
primarily used to provide hard copy is the Line Printer
A line printer prints one
entire line of text before advancing to another line. Most early line printers
were impact printers.
Line printers 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, band-printers and chain printers. Other
non-impact technologies have also been used, as thermal line printers were popular
in the 1970s and 1980s, and some inkjet
and laser printers produce output a line or a page at a time.
