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 .
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
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 ...
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.
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [1] Inkjet printers were the most commonly used type of printer in 2008, [2] and range from small inexpensive consumer models to expensive professional machines.
By 1920, electromechanical tabulating machines could add, subtract, and print accumulated totals. [29] Machine functions were directed by inserting dozens of wire jumpers into removable control panels. When the United States instituted Social Security in 1935, IBM punched-card systems were used to process records of 26 million workers. [30]
Rickenbacker solved the problem and stayed on to head up Columbus Buggy's Dallas agency. At eighteen, he was the chief engineer, experimenter, demonstrator, mechanic, and salesman.
