The first is the printing resolution, which is directly related to the quality of the output image. The higher the resolution, the higher the image accuracy of the printer, and the better the printing quality. The second is the printing speed, which is directly related to the preheating technology, printer control language efficiency, interface transmission speed, memory size, etc. the other is the monthly printing load, printing function, printing cost, etc consider.
Black and white laser printer is generally used to print non color image text, documents, reports, etc. it is characterized by high speed, good quality, low price and low cost. There are many brands and models of black-and-white laser printers on sale in the market, so it is very difficult to choose a product with high cost performance in the vast sea of machines.
The black-and-white laser printers on the market are generally around 1000 yuan, so in terms of price, each printer manufacturer has little difference in realizing the same function. But you can’t just choose a brand you like just because of this. The cost of using the printer is much higher than that of the printer itself. Printer in the use process, mainly related to the replacement of consumables and maintenance costs. Therefore, when choosing a printer, the price on sale is only a part of the cost of the printer.
和多功能一体机不同，黑白激光打印机并不具备扫描、复印等功能。值得注意的是，虽然一体机具备更多功能，但产品结构也较为复杂，其后期维护较为困难。单功能的打印机由于功能单一，所以性能方面和机器能耗更占优势。因此，打印需求较大，扫描、复印需求不大的用户还是建议选择单功能打印机。当然，如今的打印机也是在不断的添加用户需要的功能。比如惠普 LaserJet Pro M104w 这款型号在打印的基础上，加上了 WiFi 的支持，可以让用户通过手机更加便捷的进行打印。
Unlike the all-in-one machine, the black-and-white laser printer does not have the functions of scanning and copying. It is worth noting that although the all-in-one machine has more functions, the product structure is also more complex, and its later maintenance is more difficult. Due to the single function of the printer, the performance and machine energy consumption are more dominant. Therefore, users who need more printing and less scanning and copying are advised to choose a single function printer. Of course, today’s printers are constantly adding functions that users need. For example, HP LaserJet Pro m104w, which is based on printing and supported by WiFi, can make it more convenient for users to print through their mobile phones.
黑白激光打印机按照硒鼓和墨粉的结合方式是分为两种的，即鼓粉一体和鼓粉分离的。比如京东上在售的惠普 LaserJet Pro M104w（鼓粉分离）、惠普 LaserJet Pro P1108（鼓粉一体）。两款的售价相差不大，但是却是从用了不同的解决方案。大家在选购的时候要注意辨别。
According to the combination of toner and toner, black-and-white laser printer can be divided into two types, one is the integration of toner and the other is the separation of toner. For example, HP LaserJet Pro m104w (drum powder separation) and HP LaserJet Pro p1108 (drum powder integration) are on sale in JD. The prices of the two models are similar, but they use different solutions. We should pay attention to distinguish when we buy.
Another important function provided by the single function printer is whether it can automatically print on both sides. A reliable printer, naturally, is to save the user’s mind. It can realize automatic double-sided printing, reduce the steps of user operation, and greatly improve the printing efficiency.
Now that the machines have been moved home, we have to consider the cost of using them. The use cost mainly includes the cost of replacing consumables and the cost of machine maintenance.
The cost of toner cartridge and other consumables. Due to different brands, the same brand of toner used by different models are not universal. Therefore, when choosing the machine, we need to pay attention to the model and cost of its supporting consumables. Of course, in order to reduce costs, many users will choose third-party consumables. Therefore, when choosing a printer, on the one hand, users can pay attention to the price of the original consumables. If they feel that the price is difficult to accept, when they want to replace the third-party consumables, they should pay attention to the popularity of the third-party toner cartridge of this printer. If there are few choices in the market. This is not worth the loss.
When the cost is fixed in a range, the printing quality will be the most important factor to determine the success or failure of this printer. After all, no one will spend money on a pile of waste. The printing resolution above the machine parameter configuration is the main reference for users to judge whether the machine is good or bad. But don’t be superstitious. After all, we should speak with actual quality.
Is the actual performance of a single function printer able to meet the printing needs of users? The benchmark is mainly the following aspects: the output time of the home page, the speed of continuous output, the monthly printing load and so on.
For the internal configuration of hardware, it often affects the actual performance of the printer. As mentioned in the performance section above, let’s talk about external configuration. For example, the capacity of the paper feeding box, the paper feeding mode and the capacity of the paper feeding box are very important. It is very helpful for the larger feeding carton with continuous operation.
Today’s life, we have been inseparable from the network. Therefore, when we choose a printer, we must pay attention to whether the printer supports wireless direct connection and other functions. These practical functions will play an important role in the actual use.
For the first time to install a printer, novices are not familiar with how to load the driver, so it is particularly important to let users start quickly. In addition, there are two types of drum powder separation and drum powder integration on the market. Of course, when the toner is used up, the drum powder integration machine needs to be replaced as a whole. And the drum powder separation type, after using toner, you can add powder operation, of course, the implementation of powder operation or need to have a certain hands-on ability.
Brand is the comprehensive embodiment of product quality, service, reliability and performance. Choosing the right brand means half success. Well known brands have achieved a high level in all aspects after years of efforts and quality assurance.
The quality of service directly affects the use and production efficiency of customers. Good pre-sale service is convenient for customers to buy, good in sale service is convenient for customers to use, and good after-sale service is convenient for customers to maintain.
3. Print braid rate
激光打印机的打印质址是用 DPI (Dots Per Inch)来衡址，即每英寸上有几个点。DPI 的值越大.说明打印的效果越好，打印的图像越细致，当然价格也越高。现在的激光打印机一般为 60ODPI, 1200DPI.
DPI (dots per inch) is used to balance the print quality of laser printer, that is, there are several points per inch. The larger the DPI value is, the better the printing effect is, the more detailed the image is, and of course, the higher the price is. Now the laser printer is generally 60odpi, 1200dpi
4. Printing speed
反映激光打印机的速度参数是 PPM (Page Per Minute),即每分钟打印的页数。PPM 值越大，说明打印机打印速度越快.当然价格也越高。
The speed parameter of laser printer is ppm (page per minute), which is the number of pages printed per minute. The larger the PPM value, the faster the printer printing speed. Of course, the higher the price.
5. Print interface
所谓打印接口，是 PC 将需要打印的文件或图像经过处理，转换成打印机能够接收的格式。通过电缆传送打印机，打印机打印出图像。打印机目前主要有两种接口,并行接口和 USB 接口，目前使用多的是 USB 接口。
The so-called printing interface is that the PC processes the files or images to be printed and converts them into the format that the printer can receive. The printer transmits the image by cable. At present, there are mainly two kinds of interfaces for printers, parallel interface and USB interface. At present, USB interface is widely used.
6. Paper size
现在窄行激光打印机可以打印 A4, B5 型复印纸大小的文稿，而宽行激光打印机可以打印 A3, B4 型复印纸大小的文稿。如果你需要打印机较宽的图像.表格的话，就需要购买 A3 的激光打印机。对于一般办公室和家庭使用，购买 A4 激光打印机已能满足需要。
Now narrow line laser printers can print A4, B5 copy paper size documents, while wide line laser printers can print A3, B4 copy paper size documents. If you need a printer with a wider image. Form, you need to buy an A3 laser printer. For general office and home use, the purchase of A4 laser printer has been able to meet the needs.
Precautions for purchase
1. Before purchasing the black-and-white laser printer, users must understand their own needs and must not be blind. If a dealer recommends the laser all-in-one machine to you, be sure to consider whether you really need the copy, scan or fax function. If you don’t need it, it’s a waste of money.
2. Be sure to search the latest transaction price on the Internet before purchasing, so as to have a clear idea. When you buy, you should carefully check the outer packaging, which must be intact without any traces of use. Check the internal accessories, especially the selenium cartridge, to confirm the model, capacity, whether the original goods are available, and whether they have been swapped.
3. At present, the competition in the printer market is fierce, and the profit has actually dropped to a relatively low level. When bargaining with the dealers, we must pay attention to the skills and not be too ruthless, otherwise they may cheat in other aspects and make you suffer a dumb loss.
4. In order to facilitate the quality assurance, it’s better to ask the dealer to issue a formal invoice for you. Don’t save the money of those tax points, which will cause great trouble in the future.
