使用PrintToPrinter方法时，Crystal设计时显示的Crystal报表不打印

嗨聪明的人，

我遇到了问题，我无法在互联网上找到解决方案 .

Problem ：PrintToPrinter方法的打印方式与Design不同 . 但是在水晶报表查看器中从水晶报表的预览打印时打印输出相同，但是用户不想在Windows窗体上单击打印并在打印预览（Crystal Report Viewer）中再次按打印 . 所以基本上我想直接将报告打印到打印机而不再询问用户 .

Page setup ：

页面大小为：8.5 * 8.5英寸 . 没有打印机（针对屏幕尺寸进行了优化）：检查了分离格式页面尺寸和打印机纸张尺寸：已检查用户定义尺寸：已选中

CrystalReportViewer的打印输出是所希望的 . 但PrintToPrinter方法的印刷纸张有所不同 .

请帮助我，我被卡住了 .

EDIT: 以下是 btnPrint 的事件处理程序 . 我希望用户在Windows窗体上单击 btnPrint 并希望打印出来 . 没有任何其他步骤 . 打印出来但不是预期的 .

如果在用户单击Crystal报表查看器上的打印按钮后单击 btnPrint 打开Crystal Report Viewer，并在选择打印机单击打印对话框上的打印按钮后，打印机将按预期打印 . 但是，消除这些步骤并不像以前那样打印 .

希望你能理解@aMazing
