问题描述
我想知道一些与生成二维码有关的信息......
如果在没有任何应用程序的情况下打印固定格式，如何动态生成可变二维码触摸应用程序本身就像虚拟打印机驱动程序...
要求是在没有任何编程或与应用程序集成的情况下完成它，因为它是一个核心银行系统...所以我正在寻找一个处理打印作业假脱机文件的解决方案 - 当出纳员打印表格时SPL - 选择虚拟打印机驱动程序然后需要的工具打开假脱机文件并读取变量数据 - >生成QR码--->将其打印为右上角的图层...
可变数据为交易编号

变量数据为交易编号
< blockquote>您首先需要了解打印文档的结构，然后找到一些方法来识别该内容中的事务（或其他）值。可能有一种方法可以通过 Print Spooler API来实现功能（Windows） [ ^ ]。或者，您需要将设备过滤器写入打印机，并在将数据发送到驱动程序时捕获数据。这些都不是一个简单的解决方案。
I would like to know some information related to generating QR code...
How can generate variable QR code on the fly when printing fixed form any application without touching the application itself something like virtual printer driver...
the requirement is to have it done without any programming or integration with the application because it is a core banking system... so I am looking for a solution to deal with print job spool file - SPL when the teller print the form - Chose virtual printer driver then the needed tool open the spool file and read the variable data --> generate the QR code ---> print it as a layer on the top-right...
The variable data is Transaction Number

The variable data is Transaction Number
You would first need to understand the structure of a print document, and then find some way of identifying the transaction (or other) values inside that content. There may be a way of doing it through the Print Spooler API Functions (Windows)[^]. Alternatively you need to write a device filter to the printer and capture the data as it is sent to the driver. Neither of these is a simple solution.
