Printing method for carrying out online design and preview based on WEB

Abstract

The invention provides a printing method for carrying out online design and preview based on WEB in the field of hospital receipt and report printing, which comprises the following steps of: step S10,creating a database for storing printing templates on a server, and creating a plurality of printing templates and storing the printing templates in the database; step S20, sending a printed HTTP request, service data and a template code to the server in WEB; step S30, enabling the server to load a corresponding printing template according to the received HTTP request and the template code; S40,enabling the server to update the service data into a corresponding printing template through a template engine, generate printing data and send the printing data to a client; and S50, enabling the client to preview and print according to the received printing data. The method has the advantage that receipts and reports can be finely printed without installing an ActiveX plug-in.

Description

technical field [0001] The invention relates to the field of hospital receipt and report printing, in particular to a printing method for online design and preview based on WEB. Background technique [0002] The main customers of the hospital resource planning system (HRP system) are the managers of provincial and county hospitals and traditional Chinese medicine hospitals. Due to the different management methods of each hospital, the required printing formats for the same type of documents are different. Therefore, the hospital resource planning system needs to be able to design a document format that meets the daily use according to the document scheme of each hospital, and needs to support the printing of various complex report data in the hospital resource planning system. [0003] Traditionally, there are the following methods for document and report printing: [0004] Method 1: Print through the print function menu of the browser; this method has the following disadva...

Problems solved by technology

[0004] Method 1: Print through the print function menu of the browser; this method has the following disadvantages: the browser determines the paging position by itself according to the page size set by the user and the content of the web page, resulting in inaccurate paging and the existence of footers Header noise, margins not aligned correctly with printed text, and non-continuous printing

[0005] Method 2: print through webbrowser control + javascript; this method has the following disadvantages: this method is still a program call of the browser's print function menu, and the browser's print function can be called directly through a button or link in the web page The menu has the same disadvantages as method one

[0006] Method 3: Print through print css, that is, embed printing-related css styles in the html document to control the output and printing of html documents, such as setting paper size, paper vertical and horizontal orientation, printing margins, and pagination, etc., but the current browsing The browser does not support this method well, so programmers cannot use print css for actual development

[0007] Method 4: Print through a PDF file, that is, download a PDF file stream from the server, open it with an adobe plug-in in the browser, and then use the adobe print menu to print; this method has the following disadvantages: it cannot be printed directly, it needs to be downloaded Adobe plug-in, some environments that can only use the local computer may not be able to print, and the existing programming language lacks good technical support for PDF generation and complex page control, and it is difficult to accurately control the printing position of the content in the PDF document
