Although with the development of electronic technology, "paperless office" is becoming a trend, but in the daily work, most enterprises and institutions still use a large amount of printed matter. Such as documents and notices in the party and government organs, papers in schools, publicity materials in commercial units, quotations, etc. This type of printed matter is often dominated by black and white papers, the number of requirements is relatively large, and the accuracy requirements can be relatively lower. Take the school's test paper as an example. The original method is to use the mimeograph. Although it is now possible to print the wax paper using a dot matrix printer (not to be etched with a stylus and a steel plate), the way of mime printing is too old, speed. Slow, poor quality of printing, the shortcomings can be said to be a lot.
Some people say, can't you use a copier or a printer? Yes, the printing quality of these two devices is very good, but the first use cost is high, the second speed is slow, and if the number of prints exceeds 50, it is obviously not suitable. In fact, there is a kind of equipment that is aimed at the current situation. The user group that this application requires, this is the printer.
The speed printing machine works by digital scanning and thermal plate making imaging, and the printing quality is clear. The printing speed of mainstream models can reach more than 100 per minute. At the same time, it also has a variety of functions such as zoom printing, splicing printing, automatic paper separation control, etc. Most models can also support the function of computer printing direct output. So what are the main technical indicators of the printer? What problems should you pay attention to when purchasing?
One. Main technical indicators
1. Printing format
Like printers, the printing format is also a primary consideration when purchasing a printer. If other technical techniques are worse, you may be able to reluctantly, but if the format of the printer is too small, there is no way. You can't ask the B4 format printer to print out A3. The document of the format comes.
There are two types of printing media for the printer: the original supports the web, the paper output, and the printed output. The original support format refers to the maximum scanning width of the printer's desktop. The paper output format refers to the maximum output paper that can be used by the printer. The print output format refers to the maximum format of the document that the printer can output. Knowing that any print is impossible to print a piece of paper, you have to leave some margins (I would like to know this concept very well for users who have used Word).
At present, the mainstream printing machine input format is basically B4 ~ A3 format, and the output format is basically A3 format.
2. Paper quality
Because of the large number of printing presses, the ability to support more economical paper is directly related to the cost of use. A good printer should be compatible with a variety of quality papers, so that you can meet the needs of different users and different applications!
3. Printing speed
In addition to the low cost of the copier, one of the biggest advantages of the printer is its printing speed. At present, most of the printing machines can achieve printing speeds of more than 100 sheets per minute, and there are also multiple speeds for users to choose.
4. Printing clarity
The clarity of printing is related to the quality of printing. Like the printer, it is also marked with dpi, but the accuracy index does not need to be as high as a printer. Generally speaking, 300~400dpi is enough!
5. Supported zoom ratio
This indicator is the same as the copier, which can enlarge and reduce the original and print it. There is no doubt that the larger the range of zoom ratios, the better. However, it should be noted that some products are graded, that is, it specifies several fixed ratios, while some products are infinitely scaled. The scaling can be defined by the user and can be accurate. 2 to 3 digits after the decimal point. Of course, the latter is much stronger than the former.
Two. Buying actual combat
1. Focus on key technical indicators
There are many technical indicators for quick printing machines, but the key technical indicators that users should pay attention to when purchasing. Because they determine the basic performance of the product. In particular, the quality of the paper used, for some users who have a very large demand for printing, and who do not have high demand for paper (such as the school used to print the test paper), the product that can support the more economical paper can make the user A large reduction in the cost of use.
2. Choose the functionality of the product according to your actual needs
In addition to the differences in basic performance indicators, the printer also has a number of special features, different products with different functions, and the difference in function and how much directly affect the price of the product, and the difference is still relatively large . Therefore, users should choose according to their actual application needs when purchasing, carefully consider which functions are needed by themselves, and which functions are not needed by themselves, and which functions can be replaced by other devices. That is to avoid the waste of function, but also to avoid the situation where the required function is not selected.
3. After-sales service is an important factor in product purchase.
The speed of the printing machine is relatively large, so it is very inconvenient to send the repair after the failure. The door-to-door maintenance of the manufacturer is very necessary. At the same time, the printer also needs regular maintenance and maintenance, which are part of the after-sales service. Users must consider when purchasing, and do not bring big troubles to themselves.
