Embodiment 1

[0028] figure 1 A schematic diagram showing the working principle of a typical laser printer. Such as figure 1 As shown, the printer can include a laser 11 for emitting a laser beam; a mirror 12 for reflecting the laser beam to a photosensitive drum 13; a charging roller 14 for charging the printing roller 13; a developing roller 15; a pair of fixing rollers 16 (upper and lower rolls); and a transfer roll 17 . The printing paper 18 is conveyed to a pair of fixing rollers 16 after passing through the transfer roller 17 . The fixing roller 16 is provided with heater lamps (not shown). Apart from figure 1 In addition to the components shown in the printer, the printer may also include other known components, such as paper trays, paper feed mechanisms, and the like.

[0029] The printer may also include a control system, such as a controller, data interface, display, and the like.

[0030] Because the printer needs to heat the printing paper during the printing process, when...

Embodiment 2

[0044] In addition to reducing the temperature through the printer control method in Embodiment 1, other methods can also be used to reduce the temperature. Figure 4 A schematic structural diagram of a printer according to an embodiment of the present invention is shown. Such as Figure 4 As mentioned, in addition to the components that can be found in a typical printer, the printer can also include ventilation located in the paper exit area of ​​the printer. The ventilation device may include at least one side air outlet 41 inside the paper output area of ​​the printer and an air supply device inside the main body of the printer. The air supply device may include, but not limited to, a fan, an air pump, and the like. In one example, the shape of the air outlet 41 may be a slot on at least one side inside the paper output area. In another example, the shape of the air outlet 41 may be a plurality of air outlets on at least one side inside the paper output area. Those skil...

Abstract

The invention relates to the field of printers, and discloses a printer which comprises a communication interface, a storer, a printing mechanism, and a controller. The communication interface is usedfor receiving multiple queued printing tasks; the storer is used for storing a mapping table of workloads and printing speeds; the controller is used for controlling the printing mechanism to executethe printing tasks; and the controller is configured to be used for analyzing a received current printing task and a next printing task so as to obtain a first workload and a second workload, when judging that the first workload is larger than a set threshold, retrieving the mapping table from the storer, and dividing the current printing task into multiple continuous sub tasks, controlling the printing speed according to the mapping table and the first workload, after executing the current sub task, executing the next sub task in a delayed mode, and when judging that the sum of a workload ofthe final sub task and the second workload is larger than the set threshold, after executing the final sub task, executing the next printing task in a delayed mode.

Description

technical field [0001] The present invention relates to a printer. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element hits the paper, it can be divided into impact printers and non-impact printers. According to the structure of printing characters, it can be divided into full-size character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, it can be divided into serial printers and line printers. According to the technology adopted, it is divided into printers such as cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and light-emitting diode. However, the current commonly used printers may encounter various pr...
