What kind of paper do most dot matrix printers use?
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.
When is a dot-matrix printer used?
A dot matrix is known as an "Impact Printer" in which pins (usually 9 pins or 24 pins) are fired against an inked-ribbon (as used in typewriters). This enables the use of multi-paged, continuous, listing paper to be used in an office, and can be left unattended to complete long print jobs. A tractor roller, that has pegs that engage with holes punched both sides of the paper, will draw the paper through the printer. If a rubber roller is used, instead, standard A4 single-sheet paper, or two pages with a carbon sheet between, can be fed into the printer either by hand or from a paper storage tray.
Definition of roller support?
Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface can be horizontal, vertical, or sloped at any angle. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. Roller supports are commonly located at one end of long bridges. This allows the bridge structure to expand and contract with temperature changes. The expansion forces could fracture the supports at the banks if the bridge structure was "locked" in place. Roller supports can also take the form of rubber bearings, rockers, or a set of gears which are designed to allow a limited amount of lateral movement.
What is the quality of do-matrix printer compared to?
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.
What paper feed mechanism are used for dot matrix?
Known as a tractor feed, in which a roller with pegs that engage in holes punched along both edges of the paper, is used to move the paper through the printer. The paper used is normally continuous fan-fold listing paper. The second type of dot matrix is one that has rubber rollers instead of a tractor feed. Here, single sheets or two sheets with a carbon sheet in between, can be either hand fed or auto fed from a paper tray. A detachable tractor feed tool can be fitted if continuous listing paper is to be also used on this type of dot matrix printer.
