Dot-matrix printers are now ( as of 2005 ) rapidly being superseded even as receipt printers.

Dot-matrix thermal-transfer printers offered more consistent color quality, but consumed printer film, still more expensive.

* Optional peripherals: 55 key full-size keyboard, Floppy disc drive, Thermal and Dot-matrix printers, Joystick

Platens are also used in some printers, such as the Dot-matrix printer.

Network printers have built-in network interfaces can serve any user on the network.

Some printers can print documents stored on memory cards or from digital cameras and scanners.

Multifunction printers ( MFPs ) include a scanner and can copy paper documents or send a fax ; these are also called multi-function devices ( MFD ), or all-in-one ( AIO ) printers.

Solid ink printers can produce excellent results.

The advantage of dot-matrix over other impact printers is that they can produce graphical images in addition to text ; however the text is generally of poorer quality than impact printers that use letterforms ( type ).

Dot matrix printers can either be character-based or line-based ( that is, a single horizontal series of pixels across the page ), referring to the configuration of the print head.

Some dot matrix printers, such as the NEC P6300, can be upgraded to print in colour.

Some printers can process all three types of data, others not.

* Character printers, such as daisy wheel printers, can handle only plain text data or rather simple point plots.

* Modern printing technology, such as laser printers and inkjet printers, can adequately reproduce all three.

Certain inks, such as those used in digital printers, and even those found in a common pen can be harmful.

These inks can be used in inkjet printers and produce electrically conductive patterns.

What's more, the polymers can be processed using low-cost equipment such as ink-jet printers or coating equipment employed to make photographic film, which reduces both capital and manufacturing costs compared with conventional solar-cell manufacturing.

On high-end printers, PostScript processors remain common, and their use can dramatically reduce the CPU work involved in printing documents, transferring the work of rendering PostScript images from the computer to the printer.

Modern computer-monitors typically display about 72 to 130 pixels per inch ( PPI ), and some modern consumer printers can resolve 2400 dots per inch ( DPI ) or more ; determining the most appropriate image resolution for a given printer-resolution can pose difficulties, since printed output may have a greater level of detail than a viewer can discern on a monitor.

However, for printing technologies that perform color mixing through dithering rather than through overprinting ( virtually all home and office, inkjet and laser printers included ), printer DPI and image PPI have a very different meaning, and this can be misleading.

Modern displays and printers are raster devices ; vector formats have to be converted to raster format ( bitmaps – pixel arrays ) before they can be rendered ( displayed or printed ).

This can result in low quality on-screen output, and the layout may sometimes change if the document is printed on a different printer ( although this problem occurs less frequently with higher resolution printers, as rounding errors are smaller ).

However, as printers have improved in quality and performance, many jobs which used to be done by professional print shops are now done by users on local printers ; see desktop publishing.

In addition, most of these printers were limited to monochrome printing in a single typeface at one time, although bolding and underlining of text could be done by " overstriking ", that is, printing two or more impressions in the same character position.

In drum printers, a drum carries the entire character set of the printer repeated in each column that is to be printed.

It could be expanded with RAM ( memory ) and ROM ( software ) modules, as well as peripherals like bar code readers, microcassette and floppy disk drives, paper-roll thermal printers, and miscellaneous communication interfaces ( RS-232, HP-IL, HP-IB ).

While supporters of the merger argued that there would be economies of scale and that the sales of PCs would drive sales of printers and cameras, Walter Hewlett was convinced that PCs were a low-margin but risky business that would not contribute and would likely dilute the old HP's traditionally profitable Imaging and Printing division.

Fernand encouraged the painters to work directly on lithographic stones in order to create original artworks that could then be executed under the direction of master printers in small editions.

The 68000 continued to be widely used in printers throughout the rest of the 1980s, persisting well into the 1990s in low-end printers.

WPS represents objects such as disks, folders, files, program objects, and printers using the System Object Model ( SOM ), which allows code to be shared among applications, possibly written in different programming languages.

It is becoming more common for large-format wide-carriage inkjet printers to be used to print onto heat-shrink plastic sheeting, which is then applied to a vehicle surface with adhesive and shrunk to fit using a heat gun, known as a vehicle wrap.

Because it was equipped with online and offline printers that were based on IBM electric typewriter mechanisms, it was capable of what, in 1980s terminology, would be called " letter-quality printing " and therefore inspired TJ-2, arguably the first word processor.

At about this time they were visited by Steve Jobs, who urged them to adapt PostScript to be used as the language for driving laser printers.

There were numerous advantages to this approach ; not only did it help eliminate the possibility of different output on screen and printer, but it also provided a powerful graphics system for the computer, and allowed the printers to be " dumb " at a time when the cost of the laser engines was falling.

Modern fanzines are printed on computer printers or at local copy shops, or they may only be sent as email.

This argued for a return to licensing, not with reference to the printers, but because without something to protect authors and guarantee them an income, " Learned men will be wholly discouraged from Propagating the most useful Parts of Knowledge and Literature ".

Devices that are exclusively for recording ( e. g. printers ), exclusively for reading ( e. g. barcode readers ), or devices that process only one form of information ( e. g. phonographs ) may or may not be considered storage devices.

A common legend states that in the second year of the Hsüan-ho, in the Sung dynasty 1120 AD, a certain official memorialized the throne, praying that the ya p ' ai ( ivory cards ) be fixed as a pack of 32, comprising 127 pips it should be 227, but Chinese printers are careless, in order to accord with the expanse of the stars and constellations.

The NBP lists were examined and displayed by a program known as the Chooser which would display a list of machines on the local network, divided into classes such as file-servers and printers.

Dot matrix printers are divided on two main groups: serial dot matrix printers and line matrix printers.

The objects fall into two broad categories: resources ( e. g., printers ) and security principals ( user or computer accounts and groups ).

His truly epochal invention was the combination of these elements into a practical system which allowed the mass production of printed books and was economically viable for printers and readers alike.

Finally, the city of Mainz was sacked in 1462, driving many ( including a number of printers and punch cutters ) into exile.

The 68000 became the dominant CPU for Unix based workstations including Sun workstations and Apollo / Domain workstations, found its way into heralded computers such as the Apple Lisa and Macintosh, Amiga, Atari ST, and was used in the first generation of desktop laser printers including the original Apple Inc. LaserWriter and the HP LaserJet.

For a time an interpreter ( sometimes referred to as a RIP for Raster Image Processor ) for the PostScript language was a common component of laser printers, into the 1990s.

As they grew in sophistication, dot matrix printers started including several built-in fonts from which the user could select, and some models allowed users to upload their own custom glyphs into the printer.

While later editions had more-or-less comprehensive installation programs that allowed selection of printers and terminals from a menu, in the very early releases, each of the escape sequences required for the terminal and printer had to be identified in the hardware documentation, then hand-entered into reserved locations in the program memory image.

They were also called 132-column printers, though this description was only true for a specific font size and type that was built into the printer's electronics.

However, not much should be read into this price difference as the printing costs for inkjet and laser printers are a great deal higher than for dot matrix printers, and the inkjet / laser printer manufacturers effectively use their monopoly over arbitrarily priced printer cartridges to subsidise the initial cost of the printer itself.

Unlike laser printers which have been criticized for their environmental emissions, line matrix printers don ’ t emit harmful particulates into the workplace.

The LaserWriter was also the first peripheral to use the LocalTalk connector and Apple ’ s unified round AppleTalk Connector Family, which allowed any variety of mechanical networking systems to be plugged into the ports on the computers or printers.

The LaserWriter and LaserWriter Plus printers included high quality, scalable Adobe PostScript-fonts built into their ROM memory.

Theophrastus ' Enquiry into Plants was first published in a Latin translation by Theodore Gaza, at Treviso, 1483 ; in its original Greek it first appeared from the press of Aldus Manutius at Venice, 1495 – 98, from a third-rate manuscript, which, like the majority of the manuscripts that were sent to printers ' workshops in the fifteenth and sixteenth century, has disappeared.

Two large printers print the pages ( left ) and the cover ( right ) and feed them into the rest of the machine for collating and binding.

His hunt for books brought him into contact with dealers, other collectors, printers and librarians.

" Sloppy printers sometimes turned this into Ouriconsing, Ouiscousen, and even Ouiskonche, but the " Ouis …" spelling was the one most often used by both French and English writers until the mid-19th century.

It is recommended that appliances that need a controlled shutdown sequence ( such as many ink-jet printers ) not be plugged into a slave socket on such a strip as it can damage them if they are switched off incorrectly ( for example the inkjet printer may not have capped the print head in time, and consequently the ink will dry and clog the print head.

Caresse printed the magazine on a variety of different sizes, colors and types of paper stock printed by different printers, stuffed into a by folder.

In the mid 20th century light industry flooded into Cremorne, with the construction of hundreds of small to medium factories, which were occupied by the rag trade, mechanics, printers and small engineering businesses.
