Abstract

The invention relates to a file printing preview method and device and a file printing system, and the method comprises the steps: obtaining a to-be-printed file; obtaining a safe preview instruction of the to-be-printed file, wherein the safe preview instruction is used for indicating to output a preview page of the to-be-printed file in a safe preview mode; in response to the security preview instruction, identifying a character paragraph in the to-be-printed file, and extracting a target character in the character paragraph according to a preset extraction rule; and generating a preview page according to the target text, and outputting the preview page. According to the file printing preview method provided by the embodiment of the invention, the security of the file in the printing preview process can be improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a file printing preview method and device, and a file printing system. Background technique [0002] At present, in the process of printing files, the user uses word or PDF software to open the file when printing, and then executes the printing task. The printing task is sent to the printer through the network or USB, and the printer directly prints out. In a scene with relatively high security requirements, when the document is opened by software, it is easy to be peeped by people near the host; or, when the file is printed, the preview image of the application software is also easy to be peeped by people nearby, resulting in The content of the printed file is leaked and the security is low. Contents of the invention [0003] Embodiments of the present invention provide a file printing preview method and device, and a file printing system, which can improve the security of f...
