Problems solved by technology

[0003] Traditional printers cannot detect the printed documents during the printing process, resulting in printed documents that may have one or more combinations of missing characters, missing images, missing forms, paper damage, and paper wrinkles. If the user finds these defects when viewing the file later, it may cause some unnecessary troubles to the user because of these defects in the file

Abstract

The invention relates to a printer which comprises the components of a printing task receiving module that is used for receiving a printing task of a user; a control module which is used for acquiringthe printing task that is received by the printing task receiving module and controls a printing module to execute printing according to the printing task; a detecting module which is used for detecting paper that is printed by the printing module in a printing process by the printing module according to the printing task and determines whether a defect exists in the printed paper, if yes, transmitting a defect signal to the control module by the detecting module, controlling the printing module to execute printing from a source file which corresponds with the paper with the defect accordingto the defect signal and the printing task, and otherwise, continuing printing by the printing module according to an original printing task; and an eliminating mechanism which is electrically connected with the control module and is used for eliminating the paper with the defect. The printer can ensure no defect of the file, thereby preventing some unnecessary troubles to the user.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a printer. Background technique [0002] A printer (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 has an impact on the paper, it can be divided into impact printers and non-impact printers. According to the structure of printed 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 is divided into serial printers and line printers, and according to the technology used, it is divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and light-emitting diode. type printers. [0003] Tr...
