Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] Please refer to figure 1 , the printing control system provided by the present invention is composed of a computer 2, a printing device 1 and an external storage device 3. The external storage device 3 is connected to the computer 2 through an interface to realize two-way communication with the computer 2 .
[0034] In this embodiment, the external storage device 3 may be a combination of a smart card (IC card) and a smart card reader (IC card reader), or a removable storage device such as USBKEY. When the above-mentioned external storage device 3 is working, it is necessary to input a password (such as a personal identification number PIN) to obtain the permission to communicate with the computer 2 . The smart card reader is connected and communicated with the computer 2 through the serial communication interface or the parallel communication interface of t...

The invention provides a printing control system, including a computer and a printing device, and also including: an external storage device. The storage device is connected with the computer to implement two-way communication with the computer. The printing control method by adopting the system includes the steps: making and distributing the external storage device with a device printing control information, and using a character processing system to generate an electronic document containing a document printing control information; reading the device printing control information and judging the legality of a printer; judging the validity of printing time limit; judging the integrity of printing record base; judging if the printable share number is greater than zero; circularly printing the document until the share is zero and exiting. The system and method effectively ensure the seriousness of printing the electronic documents.
Description
technical field [0001] The invention relates to a control system and a control method used in the computer field, in particular to a system and a method for controlling the printing of official documents. Background technique [0002] Today, with the increasing popularity of computer technology, security encryption technologies such as digital signatures and electronic official seals have been rapidly developed and widely used. For example, government agencies, enterprises, and institutions often need to issue official documents with so-called red-headed documents to their subordinate units. Electronic official documents with official seals do not need to be directly issued paper copies, and the subordinate units will print them into paper copies after receiving the above-mentioned electronic official documents. Although this method of issuing electronic documents is more convenient, since there is no restriction on the printing of official documents, the official documents...
