Print monitoring system and method for universal printer

Abstract

The invention discloses a print monitoring system and a method for a universal printer. The print monitoring system comprises a print control unit, a virtual printer driver, a server and a plurality of physical printers. The print monitoring method comprises the specific steps of: 1, mounting the print control unit and the virtual printer driver, 2, setting a key word, 3, monitoring print operation of a user, 4, forming a new print document name, 5, selecting the physical printer, 6, starting the print operation, 7, recording a print content text, 8, embedding a plaintext watermark and a two-dimensional code, 9, sending the print document, and 10, recording the key word. According to the system and the method, the physical printers are controlled on the premise of not changing allocation of the client printers, and a method effectively auditing the print content and tracing a document source is provided by checking and processing the print content.

Description

technical field [0001] The invention belongs to the technical field of computers, and further relates to a printing monitoring system and method for general printers in the technical field of printing monitoring. The invention realizes the control of the physical printer without changing the deployment of the client printer, and provides an effective method for auditing the printing content and tracking the source of the document by checking and processing the printing content. Background technique [0002] With the popularity of personal computers and printers, almost all industries that use computers generally use electronic documents to store data and convert them into paper documents through printers. This process is undoubtedly a major challenge to the confidentiality of materials and information. Existing problems include: how to control the use of printers by users to avoid paper waste and printer wear and tear; how to record the information of users who perform prin...

Problems solved by technology

And this process is undoubtedly a major challenge to the confidentiality of materials and information

Existing problems include: how to control the use of printers by users to avoid paper waste and printer wear and tear; how to record the information of users who perform printing operations and embed them into the print data, so that the formed paper documents have obvious identification and are convenient for sources Tracking; how to check the printed content, and record the printing operations containing specific keywords to facilitate content auditing

These methods have achieved the purpose of printing monitoring to a certain extent, but this method of using a specific monitoring program has the following disadvantages: First, the printing monitoring program implemented by process injection is easily considered as a virus by anti-virus software, resulting in Manslaughter or cause disruption to users

Second, the print monitoring program will generate new processes and even scan user processes, which not only takes up resources, but also many enterprises and institutions do not want to add new processes to the client

Third, there is a certain incompleteness in this monitoring method, and it cannot monitor the printing operations of certain applications or certain types of printers

Fourth, this monitoring method will not process the printed content, making subsequent tracking of the source of the document ineffective.

The disadvantage of this method is that the printers are required to be centrally deployed on the server, while in general units, the printers are usually deployed on the client computers, which will change the way the printers are deployed and cause additional deployment costs
