Small Character Inkjet Printers (CIJ printers) and Thermal Inkjet Printers (TIJ printers) are two types of coding equipment that differ in working principles, application fields, consumable usage, and more.

1. Working Principle:

   • Small Character Inkjet Printer: Uses pressure to eject ink from the nozzle, crystal oscillation to form droplets, and then charges the droplets to deflect them in a high-voltage electric field, forming dot-matrix text or patterns on the product surface.
   • Thermal Inkjet Printer: Utilizes a thin-film resistor to instantly heat the ink, creating bubbles that expand and force droplets out of the nozzle, forming the required text, numbers, barcodes, etc.

2. Application Industries:

   • Small Character Inkjet Printer: Widely used in industries such as food, beverages, pharmaceutical packaging, cosmetics, electronic components, PCB circuit boards, suitable for high-speed production environments.
   • Thermal Inkjet Printer: Commonly used for packaging identification and variable printing, integrated into automated platforms, suitable for large-area variable information coding, such as QR codes, barcodes, etc.

3. Printing Height:

   • Small Character Inkjet Printer: The printing height generally ranges from 1.3mm to 12mm, with common printing heights being 5-8mm.
   • Thermal Inkjet Printer: Has a higher printing height, with a single machine capable of printing up to 200mm in height, and multiple nozzles can be stitched together to achieve a larger range of printing.

4. Consumables:

   • Small Character Inkjet Printer: Uses ink and solvents, with ink recirculation that may result in unstable concentration.
   • Thermal Inkjet Printer: Uses ink cartridges, with ink that is used and sprayed immediately, maintaining a consistent ink concentration.

5. Environmental Impact and Maintenance:

   • Small Character Inkjet Printer: May require the addition of solvents during operation, which can have certain environmental impacts, and maintenance is relatively complex.
   • Thermal Inkjet Printer: Does not require the use of solvents, is low maintenance, and has minimal environmental impact.

In summary, small character inkjet printers are suitable for high-speed, low-cost coding needs, while thermal inkjet printers offer high-resolution, high-quality coding results. Users need to choose based on the specific application scenario and requirements.
