Whenever someone wants to buy a printer, we can always hear a conversation like this, that is, 'Of course you want to buy A, A is better than B.
After a lot of talk, people always wandered around. People were thousands of people. Are you really good at what you say? What are the criteria? In fact, whether the printers are good or bad is only when they say it. This 'they' refers of course to the long list of performance indicators in the product specification sheet.
Laser printers or inkjet printers are worth mentioning. For the time being, let's talk about the common performance indicators. They are print resolution, output speed, printing cost, print format, print interface, operability, capacity , Price and Aftermarket. Below, we will go to one by one to explain.
Print resolution
It can be said that this is an important basis for judging the output of printers. It is therefore one of the important reference standards for measuring the output quality of printers. It generally includes two dimensions: vertical and horizontal. The numerical value determines the printing effect.
Among them, the output resolution of the laser printer is almost the same in both vertical and horizontal directions; the output resolution of the inkjet printer in both vertical and horizontal directions is quite different. In general, we refer to the inkjet printer. Resolution refers to the horizontal inkjet expressiveness.
At present, the mainstream laser printers in the market have a print resolution of 600 x 600 dpi, and the higher ones can reach 1200 x 1200 dpi.
However, since laser printers may experience jaggedness on the printed paper due to shaking or other problems during operation, it is advisable to choose a laser printer of 600 dpi or more in order to ensure the printing effect; for inkjet printers, the printing resolution is higher. The more realistic the image output.
At present, the mainstream inkjet printers have resolutions of 600×1200 dpi, 1200×1200 dpi, and 2400×1200 dpi.
printing speed
Usually we use the ppm and ipm units to represent the printer's output page per minute.
Among them, ppm is usually used to measure the output speed of non-impact printers. The standard can be divided into two types: one is the maximum print speed that the printer can reach, and the other is the average output speed of the printer when it is working continuously.
Therefore, it should be noted that different types of printers may indicate different ppm in their specifications. When selecting a printer, be sure to first confirm with the seller what the ppm value indicated in the description means. .
At present, the common laser printers on the market can print at 35ppm, but those of higher prices, of course, can print more than 80ppm for large-brand laser printers.
For inkjet printers, the ppm value usually indicates the maximum processing speed that the product can achieve when processing different print content. In the actual printing process, this value is usually smaller than the ppm value of the official logo.
Speaking Printing cost In fact, this is a problem that every user must consider because the printer is not a 'one-time-insured lifetime' office equipment.
Therefore, factors such as the price of post-printing paper, the price of consumables, and the purchase price of the printer itself must be taken into account. However, ordinary users should consider choosing a product with low cost.
For example, in the case of ink jet printers, ordinary graphic documents are printed with as little black ink as possible in order to save a relatively expensive color cartridge.
In addition to the cost of the laser printer, the main use cost is the cartridge. Therefore, before the purchase, you should first understand the price and quantity of the consumables used by each brand and model, and calculate the printing cost so that it is well known.
Print format
We say that different types of printers can handle different print formats, but under normal circumstances, the printer supports both A4 and A3 formats.
For home users or small and medium-sized enterprises, printers that support A4 format are absolutely enough. For users who are frequently used or need to deal with large format, consider choosing A3 and larger format printers.
In particular, printing users who have professional output requirements, such as engineering blueprints, advertising design, etc., may consider using A2 or larger format printers to meet the daily printing needs.
Print interface
At present, the interface types of printers on the market are mainly common parallel interfaces, professional SCSI interfaces and USB interfaces. Different interface types also indirectly reflect the output speed of the printer.
Nowadays, most of the printers have already adopted the USB interface. When this type of interface printer is connected to the computer, the operation is convenient and simple. It not only outputs fast but also supports plug and play.
Operable (easy to use)
For ordinary users, they often have to face the problem of replacing consumables, printing according to instructions, and handling equipment failures. In the face of these problems, we need to consider whether the operability of the printer is strong enough. Therefore, it is easy to set up, and the replacement of consumables is simple. The type of problem that is easy to rule out is more suitable for the general public.
Paper capacity
This indicator indicates the capacity of the output tray of the printer and the capacity of the input tray, that is, how much input the printer supports, the output tray, how much paper each stack can hold, and represents the size of the printer's paper handling capacity, as well as indirect explanations. The level of automation of the printer.
Therefore, the first consideration is to support multiple types of input, output trays, and total paper storage capacity. This way, the printer can not only work on various sizes of printing paper, but also reduce the number of replacements and paper fillings. , Effectively improve the efficiency of the printer.
Price and after sales
Regardless of the type of product you choose, the price factor is the most important indicator for the buyer. Despite the old idea of 'a penny-and-a-delivery', don’t blindly pursue the highest bidder, or combine it with us. To those few important indicators, comprehensive comparison.
Finally, once again mentioning after-sales service, although after-sale is not an important performance parameter of the printer, it must be taken into consideration when selecting it, and even put it to the same position as the print quality.
For example, whether the manufacturer can provide free home repair services nationwide, especially for larger-sized printers, it is obviously unrealistic for the user to transport them to the maintenance site.
