the signal will be transmitted through the radio wave

laser pointer should be free from the interruption of the electromagnetism.
Instead, blend and combine together cartridges, toner particles in the middle of each small parcel of a blend oil particles are not only simplifies the internal structure of the machine, but also to print out the contents of the oil in a sense be greatly reduced. Network printing is accompanied by the development of network technology to develop a field of printer technology, which uses network connections instead of traditional direct interface between the printer and computer connection, the use of network printers and computer data transmission to achieve two-way data exchange between , strictly speaking, technology is actually a network printer interface to alternative technologies. In the network print mode, print server plays a key role, which implements the connection between the printer and the network, the network is responsible for receiving print data from the computer and send to the printer, and printer status information to the computer; Another print server also manage print jobs from queues on different computers. When laser pointer adopts RF, the signal will be transmitted through the radio wave.
Network printing, because the printer is directly connected to the network, so all access to network computers can access and use the printer without any intermediate links. Print in printer work process, the data transfer rate is affecting print speed of a more important factor, especially in some high-performance laser printer or color printer, the printing process the printer needs to transfer large amounts of data, data transmission rate the impact of the printing speed is very obvious. As the network data transfer rate than traditional parallel port or USB interface transfer rate is much higher, so the most direct network printing is its speed advantage. "PC World" evaluation laboratory in the years of printer product evaluation process found that some high-performance monochrome laser printers and color laser printers, print some large complex (including complex graphics, high-precision images, several special fonts) document, color documents, network printing can be clearly demonstrated its speed advantage. Is a device-independent PostScript printer language, which can define the image does not take into account the characteristics of the output device (such as printer resolution, paper size, etc.), and its text and graphics to implement the same process, which to bring a great deal of flexibility in the font.
