Question no 2.   Differentiate the following: –

(b) Drum Printer & pen Plotter

Drum Printer

An impact printer in which a complete set of characters for each print position on a line is on a continuously rotating drum behind an inked ribbon, with paper in front of the ribbon; identical characters are printed simultaneously at all required positions on a line, on the fly, by signal-controlled hammers.

(1) A wide-format inkjet printer. The paper is taped onto a drum for precise alignment to the nozzles.

(2) An old line printer technology that used formed character images around a cylindrical drum as its printing mechanism. When the desired character for the selected position rotated around to the hammer line, the hammer hit the paper from behind and pushed it into the ribbon and onto the character.

 A Pen Printer

A pen printer is real full function printer; it uses the pen’s ink as the ink cartridges for the printer. The Pen Printer is very small in size; it can easily fit in your bag, briefcase, etc. A Pen Printer is also a way to recycle because whenever our pen is out of ink we will throw it away, but you can still refill the pen’s ink if it is out of ink for the Pen Printer.

The advantages of pen printer are that they are small in size, light and portable, unlike normal printer. Pen Printer can have high quality printouts too, they are also very convenient.

Pen plotters print by moving a pen or other instrument across the surface of a piece of paper. This means that plotters are vector graphics devices, rather than raster graphics as with other printers.
