In computing, a printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers.
Email is a method of transmitting and receiving messages using electronic devices. It was conceived in the late–20th century as the digital version of, or counterpart to, mail. Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries.
A letter is a written message conveyed from one person to another through a medium. Something epistolary means that it is a form of letter writing. The term usually excludes written material intended to be read in its original form by large numbers of people, such as newspapers and placards, although even these may include material in the form of an "open letter". The typical form of a letter for many centuries, and the archetypal concept even today, is a sheet of paper that is sent to a correspondent through a postal system. A letter can be formal or informal, depending on its audience and purpose. Besides being a means of communication and a store of information, letter writing has played a role in the reproduction of writing as an art throughout history. Letters have been sent since antiquity and are mentioned in the Iliad. Historians Herodotus and Thucydides mention and use letters in their writings.
A mimeograph machine was a low-cost duplicating machine that worked by forcing ink through a stencil onto paper. The process was called mimeography, and a copy made by the process was a mimeograph.
Dot matrix printing, sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. Unlike typewriters or line printers that use a similar print mechanism, a dot matrix printer can print arbitrary patterns and not just specific characters.
The mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing.
Stationery refers to commercially manufactured writing materials, including cut paper, envelopes, writing implements, continuous form paper, and other office supplies. Stationery includes materials to be written on by hand or by equipment such as computer printers.
Carbon paper consists of sheets of paper that create one or more copies simultaneously with the creation of an original document when inscribed by a typewriter or ballpoint pen. The email term cc which means ‘carbon copy’ is derived from carbon paper.
A blind carbon copy is a message copy sent to an additional recipient, without the primary recipient being made aware. This concept originally applied to paper correspondence and now also applies to email. "Bcc" can also stand for "blind courtesy copy" as a backronym of the original abbreviation.
Registered mail is a postal service in many countries which allows the sender proof of mailing via a receipt and, upon request, electronic verification that an article was delivered or that a delivery attempt was made. Depending on the country, additional services may also be available, such as:
Optical mark recognition (OMR) collects data from people by identifying markings on a paper. OMR enables the hourly processing of hundreds or even thousands of documents. A common application of this technology is used in exams, where students mark cells as their answers. This allows for very fast automated grading of exam sheets.
Office supplies are consumables and equipment regularly used in offices by businesses and other organizations, by individuals engaged in written communications, recordkeeping or bookkeeping, janitorial and cleaning, and for storage of supplies or data. The range of items classified as office supplies varies, and typically includes small, expendable, daily use items, consumable products, small machines, higher cost equipment such as computers, as well as office furniture and art.
A typographical error, also called a misprint, is a mistake made in the typing of printed or electronic material. Historically, this referred to mistakes in manual typesetting. Technically, the term includes errors due to mechanical failure or slips of the hand or finger, but excludes errors of ignorance, such as spelling errors, or changing and misuse of words such as "than" and "then". Before the arrival of printing, the copyist's mistake or scribal error was the equivalent for manuscripts. Most typos involve simple duplication, omission, transposition, or substitution of a small number of characters.
A receipt is a document acknowledging that a person has received money or property in payment following a sale or other transfer of goods or provision of a service. All receipts must have the date of purchase on them. If the recipient of the payment is legally required to collect sales tax or VAT from the customer, the amount would be added to the receipt, and the collection would be deemed to have been on behalf of the relevant tax authority. In many countries, a retailer is required to include the sales tax or VAT in the displayed price of goods sold, from which the tax amount would be calculated at the point of sale and remitted to the tax authorities in due course. Similarly, amounts may be deducted from amounts payable, as in the case of taxes withheld from wages. On the other hand, tips or other gratuities that are given by a customer, for example in a restaurant, would not form part of the payment amount or appear on the receipt.
Carbonless copy paper (CCP), non-carbon copy paper, or NCR paper is a type of coated paper designed to transfer information written on the front onto sheets beneath. It was developed by chemists Lowell Schleicher and Barry Green, as an alternative to carbon paper and is sometimes misidentified as such.
A microform is a scaled-down reproduction of a document, typically either photographic film or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used.
In printing and publishing, proofs are the preliminary versions of publications meant for review by authors, editors, and proofreaders, often with extra-wide margins. Galley proofs may be uncut and unbound, or in some cases electronically transmitted. They are created for proofreading and copyediting purposes, but may also be used for promotional and review purposes.
lp0 on fire is an outdated error message generated on some Unix and Unix-like computer operating systems in response to certain types of printer errors. lp0 is the Unix device handle for the first line printer, but the error can be displayed for any printer attached to a Unix or Linux system. It indicates a printer error that requires further investigation to diagnose, but not necessarily that it is on fire.
Challan or Chalan is a common Hindi word that has become an Indian English technical word used officially in many professional, especially financial transactions. It usually means an official form or receipt of acknowledgement or other kind of proof document, piece of paperwork, police citation, etc. According to American Merriam-Webster Dictionary "Chalan" means voucher or invoice. Similarly, British-English Dictionary Lexico also defines Challan as noun, "an official form or document, such as a receipt, invoice, or summons", and verb, "issue (someone) with an official notice of a traffic offence" and gives several examples of their applications, which are also paralleled by the Oxford Learner's Dictionary's two separate entries on the same. Wiktionary also gives examples of the application of the word challan in southeast Asia, including its use as a verb with challaning and challaned used similarly in context and meaning to police ticketing or someone being ticketed. While most of the dictionaries talk about the meaning representing a monetary penalty which is true in most real cases, Collins English Dictionary goes one step further and defines the verb part of the meaning of Chalan as "verb (transitive), to cause to appear before a magistrate", which in reality happens only in a subset of cases of Challan when a person misses paying the Challan and the matter moves to the next step of receiving a summon from a court.
