1, Canon: Canon made the world's first inkjet printer.
Although Canon now lags behind HP in market share, Canon has more patented technologies than HP.
Canon's ink drop adjustment technology is an innovation of Canon's ink jet technology, which can eject two kinds of ink drops of normal size and half size on the same print head and one printing line.
This new print head design has two heaters. One heater ejects small ink droplets, or two heaters eject ordinary ink droplets together.
The combination of two sizes of ink drops can produce more detailed and higher quality output.
Canon's inkjet printer system, especially the print head structure and driving software, makes this fine inkjet mode possible.
Although this technology does not improve the overall resolution, it can reduce the graininess of colors and improve the output quality of photos and images.
2. Hewlett-Packard: Hewlett-Packard Company is very popular in China because of its excellent products and services.
It also has its own uniqueness in technology. Its patented HP photo gray enhancement technology is a big impact on the traditional DPI technology. On this basis, HP developed the "photo II" technology and the second generation of intelligent color enhancement technology (ColorSmartII).
The second generation of color gradation enhancement technology is to let the nozzle spray tiny ink drops of 10PL, which is impossible for the naked eye to see. Because of such small ink droplets, more changes can be produced in each pixel, reflecting hundreds of color level changes, thus obtaining satisfactory printing results on ordinary paper.
The second generation of intelligent color enhancement technology is that users can easily print the best results on various printing media without worrying about adjusting various printing parameters, which is more convenient when printing a file containing images, charts, color text and black and white text at the same time.
3. Epson: While Canon and Hewlett-Packard are proud of thermal inkjet technology, Epson developed more advanced micro-piezoelectric technology, and later introduced micro-piezoelectric inkjet printing technology and PPIS (Perfect Imaging System) technology on the basis of micro-piezoelectric technology.
Miniature piezoelectric print head technology uses the characteristic that crystals vibrate at a stable frequency when energized. By changing the voltage and adjusting the frequency of crystal vibration, the size and ejection speed of ink droplets are accurately controlled. The ink ejected by this technology is only 1/3, which makes the shape of ink drops more regular and accurate and improves the resolution.
This result realizes the coexistence of high-quality printing and high-speed printing, and has the advantages of reducing ink consumption and printing cost.
4.Lexmark: Lexmark's products are not familiar to the vast number of users in China, which may be related to its late entry into the China market, but its international status is still very high. Lexmark is a subsidiary of the blue giant IBM, so it can compete with the above three companies in technology and products.
Lexmark's patent is excimer laser cutting print head technology. Through this technology, the ink-jet hole and the pressurized cavity of ink to the nozzle can be integrated, so that the diameter of the nozzle is only one micron, so the pattern printed under this nozzle has very ideal effect.
Lexmark also developed waterproof ink. Using this ink and high-resolution inkjet printer, the printing effect can be completely comparable to that of laser printing equipment.
Purchasing principle
First of all, the printer is the same as CPU and hard disk. And it may soon be out of date after purchase, because new technologies emerge one after another. If you buy it, use it, or you might as well not buy it.
Determine the actual use of the printer you bought, and choose the printer of the required grade accordingly. If it is for general use, don't buy a professional printer. If the printer you buy mainly prints black and white manuscripts, and the quality requirements for printed images are not particularly strict, then an economical color inkjet printer is the first choice;
If the printer you buy is mainly for office use, a color inkjet printer with practical quality, function and speed is a natural choice;
If it is used for professional purposes such as design and proofing, only professional color inkjet printers can meet the requirements.
In the choice of print head, they have their own characteristics. Generally speaking, the print head with piezoelectric technology has better effect. In addition, the more spray holes on the print head, the faster the printing speed and the thinner the spray holes, which is beneficial to improve the printing resolution.
At present, most common printers use four-color ink cartridges, so try to buy this one when purchasing, because its performance is much higher than that of three colors.
Also pay attention to the interface mode of the printer. General printer interfaces include parallel port, SCSI interface and USB interface, so I won't elaborate on their respective characteristics here. In addition, there are problems such as printing noise, ink consumption, after-sales service and printer consumables cost. This requires consumers to show their eyes.
The above is some knowledge of printers, isn't it too verbose?
pity
Ha ha.
Anyway, personally, I think Epson's inkjet printer is good, and the main problem is printing consumables. Printing digital photos with a photo printer requires a lot of ink, and the consumption is relatively large. Just buying ink cartridges will be unbearable. Epson's original color ink cartridges are very expensive, even if compatible ink cartridges are used, the expenses are relatively large.
Therefore, the best solution is to adopt a continuous ink supply system. This system needs to change the printer ink box device and add a split large ink box outside the printer. Each color has its own ink cartridge which can hold a lot of ink.
When you want to buy, the more you buy at one time, the less the unit purchase cost. So is the continuous ink supply system. Calculated, its cost is much cheaper than buying a small ink cartridge separately.
Moreover, the most widely used and successfully modified continuous ink supply system on the market is Epson's inkjet photo printer series, which is also an important reason for recommending the purchase of Epson.
The only disadvantage of this scheme is the need to change the printer, which is absolutely not available in the regular Epson store, otherwise no one will buy their ink cartridges.
But in computer hypermarkets and computer markets, there are places that specialize in printers.
Epson ME300, the price is around 500 yuan, and Epson meoffice 360, around 800 yuan, the price varies. If you want to buy a better one, it costs more than 1000.
