Look before buying the printer 21 kinds of indicators interpretation – Printer indicators-it industry
1, print resolution of the indicators to judge
Printer Output of good and bad effects of a very direct basis, is also an important measure of the quality of printer output reference. Print resolution actually refers to the printer to print in the designated area, you can play the points, for inkjet printers, it means that every inch of output size can output the number of ink drops. Print resolution usually include both vertical and horizontal directions, and its specific numerical value of the print is good or bad decision or not, generally in the vertical and horizontal laser printer's output resolution in both directions is almost the same, but We can also be adjusted to control the people; and inkjet printers in both directions on the vertical and horizontal output resolution varied widely, in general, we are talking about refers to horizontal resolution inkjet printer, inkjet expression. In the current laser printer market, the mainstream print resolution of 600 × 600dpi, higher resolution can be reached 1200 × 1200dpi, this is the ordinary dot matrix printer output resolution can not be achieved. As the laser printer at work may be due to jitter or other problems will appear in the print paper sawtooth phenomenon, and therefore to ensure that printing, you should try to select more than 600dpi laser printer. For inkjet printers, the print the higher resolution, then the output results more realistic image. The current resolution inkjet printer 600 × 1200dpi, 1200 × 1200dpi, 2400 × 1200dpi these types.
2, print speed indicator, said printer output the number of pages per minute, usually with two units of ppm and ipm measured. ppm standard often used to measure the non-impact printers output speed of the important criterion, and the standard can be divided into two types, one type is that the printer can achieve the highest printing speed, is another type of printer in the continuing work The average output speed, different styles of printer to print the instructions on the indicated ppm values may be different from the meaning expressed, so we select the printer, be sure to
Sell Confirm business, operating instructions as indicated on the mean ppm value in the end what is the meaning. Laser printers currently on the market, ordinary products print speed up to 35ppm, while those high prices, a good brand of laser printer print speed can be more than 80ppm. However, the final print speed laser printer may also be affected by other factors, for example, the data transmission laser printer, laser printer
Memory Size, laser printer driver and the computer CPU performance, can affect the laser printer print speed. For the inkjet printer is, ppm value is usually expressed by the printer to print in dealing with different content can be achieved when the maximum processing speed, but the actual printing process, ink jet printers can achieve values often than the instructions provided on the ppm value smaller. Affect the speed of inkjet printing nozzle configuration is the most important factor, especially in the number of nozzles on the nozzle, if the number of sprinklers and more, then ink-jet printer to complete the task more time is needed to print short.
3, the printer is not printing cost as a one-time capital investment
Office
Equipment, printing costs, therefore naturally become print the user must pay attention to one of the indicators. Printing costs primarily consider the price of paper used in printing and ink cartridges or ink prices and purchase prices of the printer itself. For normal print users, should be considered when buying the printer to choose to use low-cost products. For example, for inkjet printers, the output if the use of black ink to black content, the relative cost savings can be a little expensive color ink cartridges, it can achieve the purpose of saving printing costs; while others do not provide a black ink jet printing products, then use these printers to output black text, it will through the synthesis of other colors to achieve the purpose of printing black writing, indicating the product selected, then the future will be very high printing costs. In addition, many types of inkjet printers, printing paper output in ordinary black and white text will have good results, but it is very rich in color image output, the need for professional printing on paper, to achieve the desired effect, so that means that the future of printing costs will increase. Therefore, we select the printer in a certain long-term perspective should choose a low-cost printer to print.
