Method and system for printing preview operation of controller client end

Abstract

The invention provides a method and system for printing preview operation of a controller client end. In the method, operation is segmented, a client end sends a previewing request to a server according to the previewing operation selected by a user, the server generates an icon image, a general-picture image and a website image according to a specific previewing command, the client end loads the previewing image every time by using each segment as a unit; and by aiming at the same page of the operation and combining three previewing modes of different dimensions of images including the icon image, the general-picture image and the website image, the data volume of the images can be controlled, and the requirement of a user for checking the image contents and observing local image details can be met.

Description

technical field [0001] The invention belongs to the field of graphics and image printing, and in particular relates to a method and system for previewing jobs on a client side of a printing controller. Background technique [0002] At present, IPMS (Integrated Performance Management System) can not only support the collection and analysis of performance data, but also use the graphical user interface to provide users with a print preview of the analysis results, and drive the printer according to the user's instructions to print the analysis results. Among them, the print preview provides convenience for users to control the printing effect and selectively print pages, so the strength of the print preview function is one of the important factors to evaluate the human-computer interaction capability of the IPMS system. [0003] For the print controller of C / S architecture, a method of previewing jobs is that the client sends a preview command, and the server performs RIP proc...

Problems solved by technology

The disadvantage of this method is that if the size of the preview image is large, the speed of image generation, local download and client loading and display will be relatively slow, especially in the case of multi-page jobs, which will affect the client's interface operation response speed

If the preview image size is too small for content inspection, the preview is meaningless

On the other hand, sometimes it is necessary to carefully check the RIP processing effect of a certain area of ​​the page, but generally the size of the generated preview image is fixed, and it cannot be realized only by enlarging the entire page
