The common terminology for micro thermal printers is as follows:
* Resolution: The number of dots that can be printed per unit length, the decisive parameter of print quality. The higher the resolution, the better the print quality. Generally, it can be measured in two units: DPI (Dot Per Inch per inch) DPM (Dot Per MM) Points per mm).
* Built-in font: The built-in font is the font stored in the non-volatile memory of the printer. If the font used for printing the document already exists in the printer, the data transmitted by the computer to the printer can be greatly reduced, and the printing speed can be improved.
* Feeding method: The way the printing paper moves in the printer. Laser printers, inkjet printers and micro-printers generally use friction feeding. The table-top needles generally use both friction feeding and reaming.
* Print Size: The paper size that the printer can print. For micro printers, it is called the paper width.
* Paper width: The width of the paper that the micro printer can print.
* Print Width: The width of the print area of ​​the micro printer.
* Paper thickness: The printer can only print a certain range of paper thickness, which is called paper thickness. If the paper exceeds or is insufficient, the paper thickness will cause many problems, such as the inability to feed paper, paper jam, poor print quality, etc. .
* Print speed: For desktop office printers, it generally refers to the number of pages printed per minute (PPM). For micro printers, it refers to the length of paper printed per second. This is an important parameter to measure printer performance.
* Copying ability: Many bills need to be printed at the same time, resulting in multi-printed paper, which is the maximum number of copies that the printer can print. The generally described method is an original + n copies. n is the value of the copying ability. Only the dot matrix printer has the ability to copy.
* Font dot matrix: Different from the vector font used by laser printers, dot matrix printers and micro printers use dot matrix fonts, and micro printers have built-in dot matrix font data. Generally, the built-in dot matrix is ​​used for printing. Font size, the size of the font dot matrix determines the number of characters that can be printed on each line of the micro printer.
* Operating temperature: The temperature range over which the printer can operate.
* Operating humidity: The humidity range in which the printer can operate normally.
* Storage temperature: The temperature range over which the printer can be stored for long periods of time.
* Storage humidity: The humidity range in which the printer can be stored for a long time.
* Print driver: A program on a computer that interprets data that an application needs to print into a print control language that the printer can recognize.
* Print control command: The computer controls the printer operation by means of the software command by printing the control language, interpreting the execution of the print data, and obtaining the print result. The print control language is the foundation for the complex functions implemented by printers. It is directly related to the quality of print input quality.
* Interface mode: The data communication method used by the printer and computer or other upper computer generally has parallel port, serial port, USB interface, IrDA interface and so on. Parallel port and USB port have high data transmission rate. They are generally used on desktop computers. The serial port has a low data transmission rate. It is generally used in micro printers. The IrDA interface is different from other methods. It does not require cables and can easily implement wireless data. Transmission, generally used in portable printers.
* Black mark positioning: Because the roll paper (continuous paper) is used in the micro printer, it is not a page of paper. Therefore, if you want to print the pre-printed ticket during printing, it will be easy to misplace if you want to print. It would be more difficult to be neatly tidy, so people later invented a technique in which black mark positioning technology was to print a black block at the beginning or end of each ticket on the roll paper. The printer detected this by photoelectric sensor. When you are in the black block, you know that the ticket has started or ended at the end, which is a good solution to this problem.
* Paper end detection: If there is no paper in the paper tray in the desktop printer, the printer will give the user or the host computer some tips. This is called paper end detection. In order to prevent damage to the printer core, the micro-printer also has the technology to achieve the same function. When the photo sensor detects that the paper has run out, it will prompt the user and stop printing.
* Paper will be tested: This is somewhat different from paper detection. Generally, this technology is only used in micro-printers, when the roll paper in the paper bin is not used up, but only a small part is left. , the user is prompted to use up the paper, pay attention to prepare to replace the paper roll.
* Paper cutting method: Because the paper is used in the micro printer, after the printing, the paper is not used up, the printed part needs to be torn off. In the early days, the paper was manually torn. Now some printers are torn by the machine. Automatic paper cutting, automatic paper cutting is also divided into full cut (all cut from the end of printing), partial cut (most of the cut from the end of the print, leaving only a small part connected to the roll paper, this It is to prevent the user from holding the printed paper and the paper flying randomly.)
* Power supply mode: divided into three modes: mains supply, power supply and battery supply. The desktop printer is powered by the mains, the micro printer is powered by the power supply, and the portable printer is powered by the battery.
