Weak current College】 【printer terminology explained】.

<br> <br> Control language: by far the most common is the Post Script language. Has been designated as the International Organization for the publishing industry use the standard page description language. In the color laser printer, it's color has its precise location ., make the printer faithfully the output image, the display on your monitor's colors and scanners scanned color better achieve harmonization. It is now widely used is the Post Script Level 2 language. <br> <br> Color saturation: Saturation refers to the output .of the package in a point (Dot) in the fullness of color, commonly referred to as color coverage ratio. Color saturation for different types of printers and their standards are not the same. It not only with the printer's design structure and work patterns, .but also with the use of print media (paper, etc.) have a certain relationship. For color laser printer, because it is extremely fine toner fuser (or hot) on paper, so to be able to easily achieve better color saturation. As .for color inkjet printers, chose to meet the quality requirements of the paper, in order to achieve the ideal color saturation. <br> <br> Grayscale enhancement technology: the technology is improving the quality of laser printer output of the more commonly-used .method. It is without altering original pixel size of the printer, the output of the grey-scale level (level). This technique primarily through the printer's ASIC chip to achieve, at the same time to increase the print controller's memory capacity for aid. .As a result of various manufacturers have chosen ASICs, adopt the solutions vary, so eventually the grayscale enhancements are very different. In a commercial product in the EPSON company MGT (Micro Gray Technology) is doing better. <br> <br> PCL: .PCL (Printing Control Language) is the HP specifications of a page description language, it prints in a Windows environment, you have to be Windows bitmap format converted to PCL format code, so the printer receives the print interpretation and implementation of the CPU. Although .other companies also have their own print control language, but its applicability as PCL. <br> <br> Print interface: print interface, early using a SPP (Standard Parallel Port) of the parallel interface, through to high-end 486, this .years of consistent policy interface is EPP (Enhanced Parallel Port: enhanced parallel interface). As the EPP than SPP increased 10 times, thus increasing popularity upon adoption. EPP is not only a good solution to a printer, high-speed transmission needs, but .also with the SPP and port compatible. Today, another high-speed parallel port ECP - (Enhanced Capabilities Port: enhanced high power interface) is already in use. Because support DMA (DirectMemory Access: direct memory access) mode, and therefore has .good prospects for development. <br> <br> Color resolution enhancement technology: this technology is available in three color series printer performance improvement: one is to make the image's edge effect to be improved; the second is to improve the image quality grayscale; .third, increase the color series. Because of the different types of printers, color inkjet printer, color laser printing Kun machine and the thermal transfer printer, color resolution enhancement technology to implement. Coupled with the affected by paper, ink, toner, and other .factors, therefore, when the resolution is raised to a certain extent, then go to the one-sided pursuit of DPI is only half done. Especially on a color printer. Because the color output per inch on more points, and do not necessarily get .better output, and other relevant factors (such as color saturation, etc.) is a very important role. <br> <br> Resolution enhancement technology: get rid of the special resolution enhancement card after some major manufacturers have implemented a this kind of .technology. The core of which is dependent on the hardware and software, without increasing (or limited) hardware costs down and increase the output quality of a technology. Use of this technology can enable printing results have improved. Early resolution enhancement technology: HP company .REt, EPSON company RITech, Apple's Fine Print, Destiny company EET, etc. Other inputs to the practical and Canon company AIR, EPSON company MGT, NEC Corporation of AMB. Resolution enhancement technology to get rid of the special resolution enhancement card after some major .manufacturers have implemented a this kind of technology.

Because it has a significant impact on the quality of the output, so the printer usually resolution (Resolution) of the grades of measured. Unit of measure is the DPI (Dot Per Inch). It .means that every inch of points can be printed. For example, a printer resolution is 600DPI, which means that its print output per inch hit 600 points. DPI the higher the value, the effect of the printed output, the more realistic the finer, .and of course the output time is longer, the price of expensive. Color resolution enhancement technology, the technology is available in three dimensionsOn the color series printer performance improvement: one is to make the image's edge effect to be improved; the second is to improve .the image quality grayscale; third, increase the color series. Because of the different types of printers, color inkjet printer, color laser printing Kun machine and the thermal transfer printer, color resolution enhancement technology to implement. Coupled with the affected by paper, ink ., toner, and other factors, therefore, when the resolution is raised to a certain extent, then go to the one-sided pursuit of DPI is only half done. Especially on a color printer. Because the color output per inch on more points, .and do not necessarily get better output, and other relevant factors (such as color saturation, etc.) is a very important role.

Early .resolution enhancement technology: HP company REt, EPSON company RITech, Apple's Fine Print, Destiny company EET, etc. Other inputs to the practical and Canon company AIR, EPSON company MGT, NEC Corporation of AMB. <br> <br> PPM (Pages .Per Minute): number of pages per minute output is color inkjet printers, laser printers (including color laser), thermal transfer printers used to measure the output speed is an important indicator. PPM value refers to the continuous average speed when printing, if you .print only one page, you also need to add Home warm-up time. Specific to a particular type of product, because the output of the object (a plain text, there is a belt of colored text and pictures with true-color, plus .coverage), combined with the manufacturer's testing standards are not harmonized, resulting in a greater difference between PPM target. In view of the PPM could only serve as a reference value. PCL PCL (Printing Control Language) is the HP specifications of a page description .language, it prints in a Windows environment, you have to be Windows bitmap format converted to PCL format code, so the printer receives the print interpretation and implementation of the CPU. Although other companies also have their own print control language, but its applicability as .PCL.

As the EPP than .SPP increased 10 times, thus increasing popularity upon adoption.
