Problems solved by technology

[0003] However, on the WinCE operating system, the program does not have its own print preview control, and Microsoft does not provide a set of standard print preview controls, so users cannot preview the effect of the document to be printed before printing, especially I don’t have an intuitive understanding of the page margin settings, and often the printed content is excessively cropped during printing due to improper page margin settings, or the image display is inaccurate
It brings great inconvenience to users and causes waste of paper resources in certain procedures

Embodiment Construction

[0027] Please combine figure 1 Shown, the flow process of the print preview method based on WINCE of the present invention comprises the following steps:

[0028] (1) Start the system and start the print preview service program as the background service program at the same time;

[0029] The print preview service program is a virtual printer driver preset in advance, and its essence is an ordinary WinCE program. Different from other normal programs, when the program starts running, it does not have a program interface, but runs in the background. The user cannot feel the operation of the program. The print preview service program includes the following modules:

[0030] System message processing module: it is the main message loop function of the program (each WinCE program can register a message processing function with the system to receive system messages), mainly used to receive various messages forwarded by the print preview driver through system messages, including :...

Abstract

The invention discloses a print preview method based on a WINCE system, comprising the following steps: the system and a print preview service program are started; a print preview operation is started, an application program registers and stores a self window handle and an instruction code used for transitive information of the corresponding print preview service program into the print preview service program into an image file; the application program can transfer a print preview drive program to perform normal print operation; a print drive is initialized, the print preview service program is informed to load the corresponding image file according to parameters attached in system information and to transfer a print preview window truly used for displaying an image after being analyzed, the print preview window reloads and displays the stored image file; and the preview data is printed and output. The invention realizes that a user can visually see and adjust the content to be printed before the print, thereby avoiding the waste of the paper resource caused by direct print.

Description

【Technical field】 [0001] The invention relates to a print preview method, in particular to a WINCE-based print preview method. 【Background technique】 [0002] As a common program control on ordinary PC programs, print preview is widely used in most PC programs. For example, Microsoft's IE and Office series software all have print preview controls, so that users can print documents before printing. preview the document to determine whether the page margins and typesetting format of the printed document meet the requirements. [0003] However, on the WinCE operating system, the program does not have its own print preview control, and Microsoft does not provide a set of standard print preview controls, so users cannot preview the effect of the document to be printed before printing, especially There is no intuitive understanding of the margin setting, and often the printed content is excessively cut or the image display is inaccurate due to improper margin setting. It brings ...
