What is the difference between printing and photocopying

The accomplishment of counting microdots can do by an optical scanner which provides two-dimensional matrix. In two dimensional matrix, each position or cell leads to a physical position which in further has two values which tell that whether ink or toner was found or detected in that place which is analyzed by an optical scanner.

Therefore, printed or photocopied both documents scanned under high resolution and low resolution, so that a representation if toner or ink present at various location on paper or not. The printed document analyzed at a low resolution which used to mark the high-resolution matrix area. Unmarked areas that left of high-resolution matrix are then analyzed to check discrete microdots that distributed uniformly in those areas.

If microdots present on the surface of paper or document it indicates that the document was photocopies or we could say, it is not original.

Toners can be different from the photocopied documents and printed documents which can be detected by various techniques like reflection-absorption infrared spectroscopy. Printed documents show sharped edge characters and smooth contrast while the photocopied document shows blur contrast and smooth edge character while analyzed.

Large grey level alterations denote DCT frequency analysis Discrete Cosine Transformation :- In small image areas, high frequencies and large areas of an almost constant grey level are for low frequencies. DCT used for the classification of paper. It did by calculating the DCT coefficient mean and standard deviations as statistical features. However, if only a few pages need to be printed, then printing becomes much cheaper. Another major difference between the printer and the copier is quality.

Printers usually produce high-quality images as they use the inkjet process which is also available in copiers but quite rare , while images are produced using xerography are low resolution. When some of us think of copying, we think of placing a sheet of paper face down on the glass of a copier and keying in quantity on the control panel, pressing start and waiting for the copies drop into a tray on the side of the machine.

Others may imagine even dropping coins into the device at a dime or a quarter a copy! The process is actually called photocopying and describes the process of transferring images and information to paper with toner, a dry agent that is transferred electrically and adhered to the page in a heated process. Copiers have evolved in the last 25 years from the descriptions above.

Copy machines with document handlers were designed to accept stacks of paper so multiple page documents could re-circulate again and again for each copy that was made. Machines got bigger and faster, accepting larger quantities of paper and going longer between paper jams that seemed to be unpreventable.

Copy machines still exist and still make copies, but most produced these days are utilized as printers connected to a network of computers and incorporated with scanning and fax capability. Colour copying too has evolved, and colour printers are becoming more common, although still more expensive to operate than basic printers.

Documents can be shared electronically now over networks and emailed from one user to another. And when paper copies are needed, the document can be sent to a multi-function printer designed to collate, staple, 3-hole punch and even stitch into booklets.

The document goes straight to the printer from the user's computer, and each "copy" is actually an original "print"! So the term "Copying" is often misused referring to "Printing", not to be confused with offset printing where images are transferred in ink from a plate to a blanket to the sheet.

But that is another story for another day. While photocopiers generally cost more upfront than copiers, the per-copy cost when running a photocopier is much less. For example, a single toner cartridge typically produces thousands of copies, while an ink cartridge only gets you to the hundreds-of-copies range.

However, the real cost to you and your business depends on how often you make copies. A good way to put everything in perspective is to determine how much it costs you to copy each page. To do this, determine how many copies you regularly make over a certain time period, such as per month. Then find out how much an ink cartridge costs as well as how many copies it yields per cartridge, on average.

Do the same for a toner cartridge. Divide the cost of the cartridge and toner by their respective yield rates, and that's the per-copy cost. Multiply that by the number of regular copies you make to tell you how much you're spending. Contact Us. Pay My Account. Invoice Usage. Remote Support. Web Mail. Customer Login. Table of Contents.

The device works in 5 steps: Charging Exposure Developing Transfer Fusing A cylindrical drum present in the machine is charged electrostatically by a high voltage corona wire.

What is a Printer? The difference between the two printer technologies lies in how they illuminate the drum: Laser printers use a laser beam that tracks back and forth across the drum, while LED printers use an array of LEDs that flash the entire line all at once.

The main difference between laser and ink printers are the type of cartridges each printer uses. Laser printers use toner cartridges while ink cartridges are used by inkjet printers. A laser printer uses an electrical charge to instruct where and when the toner should be dispensed onto the paper.

A poster is printed on an offset print machine that is capable of printing high volume at a reasonable cost. A photographic print is either printed by the photo lab on photo paper or by a high-quality photographic print machine. A printer is defined as a machine for printing text or pictures onto paper, especially one linked to a computer.

A copier is a machine that makes exact copies of something along the lines of a document, photograph, drawing, etc. For printing, the color format that is often used is called CMYK. RGB is based on 3 colors that you can see looking at any computer monitor. They are red, green, and blue. Printed documents show sharped edge characters and smooth contrast while the photocopied document shows blur contrast and smooth edge character while analyzed.

They are mostly used in forensic science to solve the forgery cases. Print media is that means of mass communication through which information is disseminated in printed form. As against this, electronic media is one in which electronic or electromechanical energy is employed to transmit information to the audience. One of the newer advancements in printing is digital printing, which was created in the early 90's. The main difference between silk screen printing and digital printing is that the digital printing process allows designs to be taken from a computer and printed directly on a shirt.

Embossing is when you press into paper or card stock from underneath. Debossing, on the other hand, is when the imprinted design causes depressions in the material leaving a depressed debossed imprint of the image on the paper or card stock. The three main types of Intaglio printing are etching, engraving, and drypoint. Explain the difference between engraving and etching. Engraving is a process of incising an image onto a hard surface such as wood, stone, or a copper plate. What's the difference between an inkjet printer and a laser printer?

An inkjet printer uses ink to print documents, while a laser printer uses a laser to print documents. Pretty simple, right? The different printing processes affect each printer's speed, functions, and image quality. Xerox is a company that patented the photostatic drum for printing and photocopying.

Now that Xerox no longer has a monopoly on the production of such machines and other companies like Canon, HP, Lexmark to name but a few manufacture laser printers and photocopy machines, they are no longer called xerox's. Screen printing is a more traditional t-shirt customization method in which each color in a design is separated and burned to individual fine-mesh screens. Embroidery refers to clothing that has a pattern or logo stitched into its fabric.

Printing is when a design or logo is printed directly onto the garment. To illustrate the difference, write int interprets the argument as a single character to be printed, while print int converts the integer into a character string.

Printing is much more expensive and only the people with enough budgets can afford having them done this way. Photocopying, obviously, is cheaper. If time is a consideration and not the quality, this is how you should go about reproducing your project. Also best for small amounts and budget-conscious people.

Difference between Impact and Non Impact Printer The main difference between Impact and non impact printers is that impact printers were the first of their kind which were used for printing documents but have become redundant. Print Preview is used to display the current document as it would appear when printed.

The main difference between the Print Preview window and the document as it is shown in Jarte's editing pane is that the Print Preview window shows the page margins and the header and footer lines, if those are defined When they borrow money, money is taken out of the consumers hand and basically shrinks money supply.

A printed medium is a news organization as newspapers and magazines producing news and stories intended to be read. The difference between print media and Print media reaches its audience only through an optical medium, while the broadcasting media reach their audience via audio and audiovisual media. As adjectives the difference between print and nonprint is that print is of, relating to, or writing for printed publications while nonprint is being or pertaining to a source not found in print; not in print.

As adjectives the difference between print and nonprint is that print is of, relating to, or writing for printed publications while nonprint is being or pertaining to a source not found in print; not in print.. Canvas prints are made by printing an image directly onto a canvas, which is then stretched or wrapped around a frame — either wrapping the image around the stretchers or using a white or coloured border. The black portions on the document do not reflect and that portion on the drum remains negatively charged.

The negative charges pick up the positive charged toner, which is then transferred on to the document and fused by heat. The document is copied and printed. Printer is a peripheral device that creates a solid copy of the digital data that is represented on the computer screen. Printers can be used to connect to a computer using a USB or wirelessly.

One printer can also be connected to many computers allowing all computers to be able to print on that printer. Many newer printers are also able to support memory cards, digital cameras or scanners. Higher end models for offices also come with other features such as scanner, copier and fax. These models are known as Multifunction printers. There are various different kinds of printers that are available.

These printers are classified depending on the type of technology is used in printing.
