Basic number is 9 pins, while 24 pins give a higher quality print.
There are mainly two types of printers,1.impact printer2. non impact printerHere impact printer contains single type "Dot matrix printer".and Non impact printer contains two type.One of them is"Inkjet printer"and second one is "laser printer".1.Dot matrix printer:-Dot matrix printer are used in carbon copy printing.The number of metal pins in the print head determines the quality of output of the dot matrix printer.(30 to 550 characters per second)
Please specify the printer type weather it is laser , dot matrix or ink jet.
9 pins
There are many price options one may consider when purchasing an Epson Dot Matrix printer. Price Grabber has many prices from various retailers one can refer to. Amazon has many available to, with price comparisons for individual vendors as well.
The dot-matrix and the daisy wheel both handle perforated carbon paper. There is a Brother printer that basically replaces the dot-matrix printer. The Brother can print up to seven copies. There is another alternative and that is carbonless paper. With that you can use ink-jet or laser printers, I believe certain models. That is your preference of either space or choice for laser or ink-jet. Carbonless paper makes 2 or 3 copies.
remote printer is these printer we can connect to many computer by using wireless comunication is called remote printer
Common kinds of printers are: Canon, Lexmark, Seiko Epson, Hewlett-Packard (HP), Kodak and Brother. Those are the only ones i can think of.
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.
The quality of a dot matrix printer depends on whether it has 9 or 24 pins. Compared to an inkjet or laser, the quality can be less. It rather depends on what the dot matrix will be used for? As an impact printer, it is mostly used to print through the pages of multi-paged, continuous, listing paper, as used in many offices. Such paper needs a tractor feed (pins on a roller engaging holes punched along the edges of the paper), and can be left unattended while printing takes place. If rubber rollers are used instead, printing can be done on A4 single-sheet paper from a tray, or hand-fed on A4 multi-pages to produce a top copy and a carbon copy.
Often used in an office, a dot matrix normally uses continuous, fan-fold, listing paper. A tractor roller (pegs on the roller engages punched holes on both edges of the paper) is used to feed the paper through the printer. This set up means that the printer can be left unattended while printing lots of data over many hours. Some dot matrix printers may have rubber rollers instead of a tractor roller. The paper used here could either be A4 or A3 single-sheet paper, or if a detachable tractor unit is clipped on to the printer, listing paper (as described above) could be used as and when required.
Several types of printers used an ink or carbon ribbon in the way you described. The daisy wheel printer and ball printer would spin a wheel that has the printable characters, then the wheel would strike the ribbon, leaving an imprint on the paper. The dot matrix printer used a number of pins that struck the ribbon to generate a printable character. The chain printer had several full sets of all printable characters on a long chain, and the chain spun rapidly on a track. As the appropriate printable character arrived at the proper location, a high speed solenoid driven hammer struck the chain, causing the ribbon to leave an imprint on the paper.
