"Barcode printing users must see" barcode printers that you don't know

Barcode printers have many parameters. What do these parameters mean? what's the function? It is estimated that many people are not clear. In order to facilitate the need for small partners to quickly understand these basic knowledge, Xiao Yang summed up some important parameters for the customers who intend to purchase for reference. Users who are using a bar code machine may also wish to take a look and improve the life of the printer.

Barcode Printer - Font

The font refers to the type and quantity of fonts that can be realized by the bar code printer without the support of the foreign font library. The fonts are divided into Chinese fonts, English fonts and some other types of fonts. Font changes can generally be achieved through buttons on the printer panel.

Barcode Printer - Interface Type

The interface type refers to the way the barcode printer is connected to the computer system. Common interface types: parallel port (also known as IEEE 1284, Centronics) and serial port (also known as RS-232 interface) and USB interface, as well as PS/2 interface.

At present, more than the parallel port and serial port are used on the bar code printer. The parallel port is also called the parallel interface. At present, it is mainly used as a printer port, and a 25-pin D-shaped connector is used. The so-called "parallel" means that 8-bit data is simultaneously transmitted through parallel lines, so that the data transfer speed is greatly improved. However, the length of the line transmitted in parallel is limited, because the length increases, the interference increases, and the data is prone to error. At present, computers are basically equipped with parallel ports.

The serial port is called the serial interface. Today's PCs generally have two serial ports COM1 and COM2. The serial port differs from the parallel port in that its data and control information are transmitted one by one. Although this speed will be slower, the transmission distance is longer than the parallel port, so the serial port should be used for long distance communication.

Barcode Printer - Memory

Because it is necessary to store the edited barcode content, it is also to improve the running speed of the product, especially the speed of printing, to save the printing task and the print task buffer in the printing task, to ensure the smooth completion of the printing task, Barcode printers have designed internal memory (referred to as memory) in the product to store user-edited content and some data that needs to be stored and exchanged when printing. Although the barcode is small, the amount of information actually contained is still relatively large. Therefore, the memory capacity of the strip printer is still relatively large, and some flash memory is supplemented.

Barcode Printer - Ribbon Length

The bar code printer's consumables are called carbon ribbons, and the length of the ribbon is naturally how long the carbon is. The longer the ribbon is, the longer its life will naturally be, and the greater the number of bar code labels that can be printed.

Barcode printer - maximum print length

In the process of bar code label printing, the bar code printer does not mean that it can print at one time without restriction, and generally has a certain limit on the length of printing. The maximum print length is also expressed in units of length units of mm, which can be said to be clear at a glance.

Barcode printer - print speed

Unlike the printing methods of our common inkjet printers and laser printers, the bar code printer print speed is expressed by the length of the widest label tape that the product can print in a unit of time. Expressed in mm/s (mm/s), that is, how many millimeters of label tape can be printed in one second. For this technical indicator, the bigger the better, the better.

Barcode Printer - Resolution

Resolution is a common indicator for all printing devices, as is the label printer. Resolution refers to the highest achievable printing accuracy of the product. That is, how many points can be achieved per inch, in units of dpi. Multiplying two numbers represents lateral accuracy and longitudinal accuracy. In general, the resolution of current bar code printers, 300dpi products are much more.

Barcode Printer - Print Width

Print width refers to the maximum width range that a barcode printer can print. Its logo is different from the size of the ordinary printer paper, but it is marked by the daily length unit mm, which can be said at a glance.

Users should choose according to the actual width of the barcode label that they need to print in the actual application. And for this problem, the user must consider it clearly, so the width can be printed small, but the width is small, it is definitely not possible to print large. There is no doubt that the print width increases and the price of the product naturally rises.

Barcode Printer - Printing Method

The printing method refers to the technology used by the barcode printer to print. In general, bar code printers use thermal transfer printing technology, and some products call themselves "hot transfer technology", which is actually a truth.

The thermal transfer technology, in a nutshell, uses a special ribbon to transfer the toner coating on the ribbon to a paper or other type of material through a working principle similar to that of a fax machine. In addition, since the coating material on the ribbon can be selected according to needs, a strong adhesion is generated, and the selection of the printing medium can ensure that the printed writing is not affected by the outside world.

Thermal transfer printing can withstand time test, long-term deformation, text can be stored for a long time, will not fade, will not wear because of contact with solvents, can not be discolored due to high temperature.
