DO IMPACT PRINTERS USE CARBON PAPER?
No. They use pins or keys to strike a ribbon that has ink on it. The ink is transferred to the paper. These are rarely seen today, having been replaced by ink jet or laser printers.
What is the tiny hammer-like keys that strike the paper through an inked ribbon called?
An impact printer
Differenciate between impact printer and a non-impact printer?
Impact printers tend to be noisy while non-impact printers are much quieter. Impact printers use either small pins or characters to strike an ink ribbon and imprint an image onto paper. Non-impact printers use some type of ink that is applied to the paper without touching it. Both laser and ink jet printers are non-impact printers.
What i the difference between an impact and nonimpact printers?
Impact printers use a 'daisy wheel' or a 'golf ball' to physically press letters through an ink ribbon onto the paper - think along the lines of an old typewriter. Non-impact printers 'squirt' microscopic drops of liquid ink directly onto the paper.
What is the difference in printers?
There are many different types of printers. Laser printers use a laser technique and toner to create the image on paper. Solid ink printer use ink stick (crayons basically) that get melted and then sprayed onto a drum and transfered onto paper. Line printers usually use a line of hammers that strike an ink ribbon to create the text. Ink printer and plotters use a printhead that moves back and forth and sprays the ink onto the media.
How do line printers work?
Line printers as well as serial dot matrix printers use pins to strike against the inked ribbon, making dots on the paper and forming the desired characters. The differences are that line printers use hammer bank (or print-shuttle) instead of print head, this print-shuttle has hammers , and these hammers are arranged in a horizontal row .The hammer bank uses the same technology as the permanent magnet print head with the small difference that instead of print wires the print-shuttle has hammers. The printing mechanism works as follow. The permanent magnetic field holds the hammer spring in stressed, ready to strike position. The driver sends electrical current to hammer coil, which then creates electromagnetic field opposite to the permanent magnetic field. When both fields equalize, the energy stored in the spring is released to strike the hammer against the ribbon and prints a dot on the paper.
Which printer type uses small hammers to strike against the paper to leave an image?
Dot-matrix printers. Daisy wheel printers have hammers (pins) that strike against raised type set around the edge of the wheel.
What destroyed the New York Herald Tribune?

What is the difference between impact and none impact printer?
Impact printers strike the paper, usually with an ink filled ribbon between the striking object and the paper, similar to an old fashioned typewriter. Non-impact printer make there impression on the paper without striking it. The can melt something onto the paper or squirt ink onto it, etc.
