Why is it said that our cylindrical printer prints faster

　　　　In fact, there are several factors that make our cylindrical printer faster:　　1: We use Ricoh G5I nozzles, each with 4 rows of holes for simultaneous inkjet printing, and a total of 12 rows of holes for three nozzles. However, ordinary nozzles only have 2 rows of holes, while three nozzles have 6 rows of holes. At the same time, our inkjet output is twice that of ordinary nozzles.　　2: If the cylindrical printer only needs to print colors, our four column hole nozzle can complete all colors at once, while a regular nozzle requires two nozzles to have four column holes. Therefore, the printed product needs to go through two nozzles to complete all colors. Our nozzle printing process is twice as long as that of a regular nozzle.　　3: When printing varnish, the lamp should not be used to irradiate the product for a long time, otherwise the varnish just sprayed on the product will not have time to flow flat and spread out, resulting in rough and uneven varnish effect. Therefore, most ma

Android System Compatibility with Wireless Printers

　　　　In the modern digital age, the seamless integration of mobile devices with various peripherals has become a necessity. Android, being one of the most widely used mobile operating systems, has made significant strides in achieving compatibility with wireless printers. This compatibility offers users the convenience of printing documents, photos, and other files directly from their Android - powered smartphones and tablets.　　Most modern wireless printers are designed to support a variety of connectivity protocols, and Android devices can typically communicate with them through Wi - Fi or Bluetooth. For Wi - Fi - enabled printers, the process usually involves connecting both the Android device and the printer to the same local network. Once connected, the Android device can detect the printer using the built - in printing services. In Android, the Print Framework simplifies this process. It provides a standardized interface for applications to interact with printers. For example, whe

What is thermal paper?

Thermal paper is a special coated processed paper whose appearance is similar to ordinary white paper. The surface layer of thermal paper is smooth. It is made of ordinary paper as the paper base, and a layer of heat-sensitive color-developing layer is coated on the surface of the ordinary paper. The color-developing layer is made of adhesive, color developer, colorless dye (or It is called leuco dye) and is not separated by microcapsules, and the chemical reaction is in a "latent" state. When the thermal paper encounters the heat-generating print head, the color developer and the leuco dye in the place where the print head prints will undergo a chemical reaction to change color and form a graphic.When the thermal paper is placed in an environment above 70°C, the thermal coating begins to change color. The reason for its discoloration also starts from its composition. There are two main heat-sensitive components in the thermal paper coating: one is a leuco dye or leuco dye; the other

Inkjet Printers for ID Photos

　　　　In the digital age, the demand for high - quality ID photos has grown significantly. Inkjet printers designed specifically for ID photos offer several distinct advantages. These printers are engineered to produce accurate color reproduction, which is crucial for representing skin tones and other details precisely. For instance, when printing a passport photo, the printer must accurately capture the natural color of the subject's face, ensuring that the photo meets the strict requirements of identification authorities.　　Resolution is another key factor. ID photo printers typically boast high - resolution capabilities, often reaching up to 4800 x 1200 dpi or even higher. This high resolution allows for the sharp reproduction of details such as hair, eyebrows, and facial features, resulting in a clear and professional - looking ID photo. The printers are also equipped with advanced color management systems. These systems ensure that the colors printed on the paper match the digital i

Development of Printer SLA Contracts

A Service - Level Agreement (SLA) for printers is a crucial document that defines the expectations, responsibilities, and performance metrics between the service provider and the client. Developing a comprehensive printer SLA contract is essential for ensuring smooth operations, maintaining print qu
