Abstract

The invention relates to a printer, which comprises a main control module, a sensing module connected with the main control module, a communication module and a printer electric module, wherein the main control module comprises an ASIC chip and a printing property realization module which is connected with the ASIC chip and can realize the identification of the printing property by a common person. By the printer, the obvious printing property which can be identified by the common person can be obtained on a print document, so that the common person can trace to the printer printing the printdocument by the print document; and simultaneously, by taking the printing property as the identification standard, the printer is supervised, thereby achieving the aims of anti-counterfeiting and anti-tampering.

Description

A kind of printer

Technical field

The present invention relates to a kind of printer, more particularly, relate to a kind of printer that has the printing feature module, make and to trace back to printer from the printing feature that is printed document, search with the clue that helps to be printed document.

Background technology

Printer is the important output equipment that is widely used in the computer office system, realizes the purpose that electronic document is exported in the paper spare mode of needs by printer.

Say that strictly each printer all has the printing feature that is different from another printer, can trace back to the printer of printing this printing document from the printing feature of printing document, significant for searching trail of evidence.But, for existing printer, particularly for the printer of same model, it is extremely a specialty and an elaboration that the printing feature of identification printing document is pursued printer, sometimes also need just can carry out, be difficult to accomplish for layman's ordinary person by means of the analysis Instrument equipment of specialty.

Summary of the invention

The technical problem to be solved in the present invention is, a kind of printer is provided, and the printing feature that will print document by its printing feature module significantly indicates, and makes the ordinary person promptly can discern the printing feature of printing document and prints the tracking of machine clue.

The technical solution adopted for the present invention to solve the technical problems is: construct a kind of printer, comprise the main control module, the sensing module, communication module and the printing electromechanical module that are connected with this main control module, described main control module comprises asic chip, it is characterized in that: also comprise the printing feature realization module that is connected and realizes the output print feature with described asic chip.

In printer of the present invention, described printing feature realizes that module is the feature printhead, this feature printhead is a needle type print head, this needle type print head comprises that at least a head is the feature print needle of non-geometry of the circle shape, and described feature print needle is arranged according to unique arrangement mode and/or arranged according to unique arrangement orientation.

In printer of the present invention, the non-geometry of the circle of the head of described feature print needle is shaped as cross, quincunx, oval, semicircle, square or rectangular.

In printer of the present invention, described printing feature realizes that module is the printing feature module, and this printing feature module comprises to be obtained characteristic information, generate unique feature string and be printed on the document.

In printer of the present invention, described characteristic information is for being printed one of document, printer ID and printer clock or its combination, and described feature string is that described printing feature module is obtained the digital signature that characteristic information generates.

In printer of the present invention, described printing feature realizes that module is feature printhead and printing feature module, described feature printhead is a needle type print head, this needle type print head comprises that at least a head is the feature print needle of non-geometry of the circle shape, and described feature print needle is arranged according to unique arrangement mode and/or arranged according to unique arrangement orientation; Described printing feature module generates unique feature string and is printed on the document.

Implement printer of the present invention, compared with the prior art, its beneficial effect is:

1. can print the remarkable printing feature that the acquisition ordinary person can discern on the document, make the ordinary person trace back to the printer of printing this printing document from printing document;

2. be judging standard with the printing feature, printer is carried out supervision, can reach false proof, anti-tamper purpose.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
