Dot Matrix printers are a kind of impact printer, which is not used nearly as much as it once was. However, they still have their uses since printing is inexpensive and they can produce multiple copies using thermal transfer or carbon paper. Unfortunately, these printers are very noisy, offer poor print quality, and use proprietary ink cartridges. When printing:
Dot Matrix printers are a kind of impact printer, which is not used nearly as much as it once was. However, they still have their uses since printing is inexpensive and they can produce multiple copies using thermal transfer or carbon paper. Unfortunately, these printers are very noisy, offer poor print quality, and use proprietary ink cartridges. Rather than having set dies for each letter, as some early impact printers did, a dot matrix printer uses pins to form the desired shapes. When printing:
#The top edge of a continuous sheet of pin fed paper is aligned just above the print head
#The top edge of a continuous sheet of pin fed paper is aligned just above the print head
#The print head moves from side to side, rapidly extending and retracting pins where marks should appear on the paper.
