how laser printers work ?

wireless printer

Understanding the principle of black and white laser printer is to understand the basis of color printing, you can use multiple images to illustrate the transformation process of its implementation. Bitmap original variable. Laser printers print the page bitmap bitmap to an image processor and then converted into electrical signals sent to the laser scanner unit. Rates "negative image" floating bitmap in the laser scanning unit, the page bitmap image points are converted into the transmission signal on the laser image drum, corresponding to a bitmap image for each pixel, a value pixel of the presence of the laser beam emitted without fireproof value.

 Lasing when the imaging drum for generating a light spot small, the image drum with a load in advance, the laser beam irradiation point is downloaded and not the metering is still in charge, through this process, the page bits contained in imaging drum becomes the charge of "negative image". Charge "negative image" of a toner "and" cartridge and imaging drum with the nature of the load, the rotation of the imaging drum, the charge roll "negative image" through images, the point to download will be absorbed by the toner charge, which is the discharge point is not absorbed as homosexual repel toner, so that the position of the "negative image" became a toner cartridge "ace". Cartridge "and" an image in a sheet of paper with the image transfer drum is also responsible of drum rotation through drum a transfer paper, the toner is adsorbed on paper as printed images. As the toner easily, printing paper through a heater to cartridge tightly adsorbed on the paper roll. As color laser printers use 4 color toner, so that the first charge on the "negative image" and toner "and" the formation of steps is repeated four times, each time on the adsorption of different colors of toner , an end product of the transfer roll is formed, a dark yellow green image, four colors. It is precisely because it is a color laser printer is repeated four times in steps, so that color printing is much slower than the speed of printing in black and white. The latest technology of color laser printing technology is called "time image".

 The key to this technology is the need for an LED laser is small enough, the light pipe in an existing location to put four colors corresponding to the four LEDs. Currently this technology is too expensive, so a "one-image" of the color laser printer, a normal user can afford, but there is no doubt that this is the future direction of development. TV, film synthesized by self-luminous colors, the composition law known as the principle of "additives", the three primary colors red, green secondary color blue as "white." Printing, coating is formed by the absorption of a certain color of light, so that the so-called "subtraction theory" law is tricolor, products, yellow green side as "black." Color laser printer color, end is how the synthesis of negotiation? HP technology as an example for analysis. technology HP Color Layering technology ImageRet2400 is used. Determine whether the basic printing 600dpi resolution images of resolution 600 dpi can be calculated, the distance between the centers of 42 micron pixel. HP 5 microns in diameter ultra-fine toner UltraPrecise, in fact, the results can be achieved 2400DPI, 2400DPI resolution when the central pixel spacing between about 10 microns . other words, if the end result is the pixel resolution of 600dpi color printing, then a pixel, you can use 16 × 16 blue, products, yellow and black toner particles with four blank to modulate pixel color because that the human eye can not distinguish the color of fine particles, so that the human eye to see the overall effect is, after mixing. This technology can provide the number of colors in the end, is calculated by permutation and mix in a classic example: A green products, colors, yellow, white and black packaging endless five bullets in five bottles China is now free to work off 16 balls in an empty bottle, the total will solve all possible outcomes? Calculate the theoretical value is ImageRet2400 technology to achieve the number of colors, depending on the constructor argument is that hundreds of thousands of people.

Wired And Wireless Printers

 Wireless Printers

The printers are common in homes and offices around the world and come in various shapes and sizes with a number of different features to meet the needs of any user. One of the most interesting features are introduced in print in recent years is wireless. Wi-Fi is something that most of us are familiar with regard to computers and smartphones, and the ability to connect to the Internet without using an Ethernet cable has certainly improved information technology, which allows us to use our computers laptop anywhere in the house or office. The question is: apply the same benefits of printing or you're better off sticking to a wired printer?

  Wireless Printers

RequirementsTo account for even a wireless printer, you must ensure that your system has a wireless network card (it probably will) and your home or business must have a wireless router. While it is possible to connect a wireless printer to a computer via a USB cable, the investment in this technology probably means you want to avoid the traditional method of connection.Speed ​​upSpeed ​​is a big problem when printing, especially if you need the printer to make your big print jobs. In terms of speed in the open air, it is very unlikely to find a difference between wired and wireless printers at all levels of the market. There will however be a noticeable difference in speed when multiple users are connected to the printer. With the Internet, more people are connecting to a wireless router, plus the service will be the same applies to Wi-Fi printers with people looking to print at the same time.AccessibilityThe main advantage of Wireless Printers ended cable is accessibility. Instead of requiring a separate application for each computer or queuing to connect to a printer via the USB printer port, Wi-Fi model allows users to connect to a central printer. This is obviously much more convenient and budget-friendly alternative to buying several individual wired printers.SecurityA printer cable is connected via a cable and requires no need for additional security. A wireless printer, on the other hand, appears to be another access points in the network, and must be added to a VPN secure.InkThe ink is an important factor with any printer, and the cost of cartridges not differ due to a printer that is wired and wireless. printer ink depends on the brand and size of the printer, and if you choose wired or Wi-Fi, it is advisable to opt for a continuous ink supply system.CostThe price of printers in both categories will depend on the make, model and features, however, wired printers are generally much cheaper than their wireless counterparts. If you are working from a desktop computer in an office with space for a printer, it is probably not necessary to justify the extra cost of a wireless system. If you need the printer to be stored in another room, or need access from multiple computers, however, be the best investment over.

What to look for when choosing a portable wireless printer

When it comes to choosing a portable printer, most printing companies are these days. Canon, HP, Brother or any of the other brands offer a choice of more and wider. There are printers that are capable of handling documents in black and white or full, or images that are photographic quality, or even those that can produce laser high definition output.

Of course, your specific needs will help you decide what is the right model. For example, what impression do you need? Will you need color prints or not? Is the print quality to be an important factor? And what will be the volume of printing?

Starting inkjet portable printer: Among all types, inkjet is considered the most versatile. They can be used for the production of texts, photos, graphics and. The quality and accuracy mainly depends on the dpi or dots per inch. Other dots per inch, the better the quality in terms of sharpness of images or text, and the colors and shadows in the images.

However, the dpi can vary depending on the type of ink used, as well as fonts, colors and shadows. You will need to verify the quality itself, which is best accomplished by a good reputation for a demonstration. The inkjet printers use different types of paper depending on the task you need to do, and the type of paper used can influence the quality of printing. For example, it requires photo paper for printing photos, and more onerous obligations will be used to print business letters for reports and other documents.

Or that the portable laser printer: If you need to make frequent presentations that require hundreds of pages printed, the printer portable laser would be a better choice, especially for printing in black and white. While the initial cost may be about $ 700.00, but laser printers use toners which are long-term, instead of ink cartridges, which are expensive. Therefore, if you need for printing high volume on the road, a portable laser printer will be cheaper in the end.

Maybe the thermal mobile printer is what you need: If all you need to print receipts and invoices may be a thermal printer for your needs. Initially, fax, use this method of transfer printing, but then changed toner plain paper, thermal paper as it is expensive. If you choose this printer is a good idea to find a good supplier and make economical use of paper. In general, thermal printers are less expensive compared to other printers because they do not use ink or toner.

There are very light hybrid thermal printers that can work with laptops, PDAs and smart phones, which are only 0.70 inches thick, weighing less than ten grams, and is capable of producing up to 4 ppm and 300 dpi.

Like many products available on the market today, mobile printers are another example of the growing trend of the elements that are rich in comfort and versatility, which promises to radically change the traditional work environment.
