Description

A printer with composite function

Technical field

The invention belongs to the technical field of printers, and in particular relates to a printer with a composite function.

Background technique

Laser printers are familiar to users because of their advantages of good print quality, high efficiency and low overall printing cost. However, laser printers can only be used in ordinary paper because their printing consumables are laser toner. The photo paper and the disc cover paper with smooth surface, due to the low adhesion of the paper itself, toner loss after printing will affect the preservation of the printed matter. Inkjet printers are faster and have higher quality. There are many types of papers that can be used. Ordinary printing paper, envelopes, photo papers, CD cover papers, etc. can be used in inkjet printers, but ink cartridges. The printing volume is low, the consumables are used more, and the overall printing cost is relatively high. Scanning and copying functions are sometimes used. Since the above functions are not frequently used, if each function buys a dedicated device, it takes up a lot of space and costs increase.

Laser printers and inkjet printers exist independently, and the technology is becoming more mature, and both printers continue to make technological advancements and intelligence in their respective fields, but so far there is still no printer that can combine two printing methods in the same printer. . A laser inkjet integrated printer is disclosed in CN201095216Y, which comprises a black and white laser printer and a color inkjet printer body. The black and white laser printer body and the color inkjet printer body have a common housing. The power interface and the data interface are connected to the housing, and the power interface and the data interface are respectively connected to the body of the black and white laser printer and the color inkjet printer. This patent application does not integrate the two printers, but simply combines the two printers to form a combination printer that is costly and bulky.

US 7,101,003 and US 7,503,636 disclose a laser color inkjet combination printer which includes both a printer having a high speed printing effect, such as a laser printer, and a printer having a high print quality, such as an ink jet printer, in the same housing. The laser inkjet printer disclosed in this patent has an output input port, a control system, and at least two consumables. Among them, the control system contains the processor and memory. This patent describes a combination printer that can receive tasks and print tasks through an output input port. However, there is no detailed description of how the control system specifically switches between the two prints or how to achieve combined printing. The specific structure of the combined printer is not described in detail, especially how the scanner or other equipment is. Installed in a combination printer. 2, the combination printer includes a sheet processing device for causing paper to travel in the printer, the sheet processing device continuously passing through the laser printing unit and the inkjet printing unit. An excessively long paper handling device not only reduces printing efficiency, but also makes it easier for the printer to jam and it is not convenient to clean the jam.
