How many printers you know; list them.
Inkjet printer
Laser printer
Dot-matrix printer
3D printer
Laser printer
Laser printers produce very high-quality hard copy output. The print rate per
page is very quick if a large number of pages are being printed. They rely on large
buffer memories where the data for the whole document is stored before pages
can be printed out.

Inkjet printers
Inkjet printers are used to produce good-quality hard copies. Unlike laser
printers, inkjet printers do not have large buffer memories, therefore printing is
done a bit at a time. This is why printing is sometimes paused – the whole print
job cannot be stored in the buffer, and it has to wait for the computer to send
more data.
Dot-matrix printer
Used in noisy environments, very cheap, very noisy
