Duplex printing is a feature of some computer printers and multi-function printers (MFPs) that allows the printing of a sheet of paper on both sides automatically. Print devices without this capability can only print on a single side of paper, sometimes called single-sided printing or simplex printing .
In normal half-duplex operations late collisions do not occur. However, in a duplex mismatch the collisions seen on the half-duplex side of the link are often late collisions. The full-duplex side usually will register frame check sequence errors, or runt frames. [7] [8] Viewing these standard Ethernet statistics can help diagnose the problem.
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
Duplex scanning is a feature of some computer scanners, and multifunction printers (MFPs) that support duplex printing. A duplex scanner can automatically scan a sheet of paper on both sides. Scanners without this capability can only scan both sides of a sheet of paper by reinserting it manually the other way up. Duplex scanning document ...

Duplex printing (printing on both sides of the paper) can halve paper costs and reduce filing volumes, albeit at a slower page-printing speed because of the longer paper path. Formerly only available on high-end printers, duplexers are now common on mid-range office printers, though not all printers can accommodate a duplexing unit.
Line printers print an entire line of text at a time. Four principal designs exist. Print drum from drum printer. Drum printers, where a horizontally mounted rotating drum carries the entire character set of the printer repeated in each printable character position. The IBM 1132 printer is an example of a drum printer. [19]
All printer suppliers produce their own type of ink cartridges. Cartridges for different printers are often incompatible — either physically or electrically. Some manufacturers incorporate the printer's head into the cartridge (examples include HP, Dell, and Lexmark), while others such as Epson keep the print head a part of the printer itself.
