Stimulsoft：无法在第一次打印预览中渲染条形码

Question

我在MVC Web应用程序中使用Stimulsoft Reports。报告中有一个CODE128C条形码，每页包含4个业务对象（每个项目都有一个条形码）。

当我从门户网站中点击“打印查看器”中的“使用预览打印”按钮时，只有第一页项目呈现条形码而其他项目条形码为空！很奇怪，当我再次这样做时（关闭打印对话框并点击“打印预览”再次打开它）将呈现所有页面中的条形码！

如果只有一个用户，我们可以强迫他打开两次打印预览！ :)但我们有非常无知的用户，他们可能会浪费大量的纸张！

这是Stimulsoft的错误吗？或者我必须在报表设计器中更改内容？提前谢谢......

更新： 这是报告的样本
