推荐答案

您要将打印转换为PDF吗?
如果是这样，请检查浏览器的兼容性.

如果不是，则必须检查数据库的char值或int值，这些值已设置为要在(RadioButtons)RDB中表示的标志.请检查是否从Backend中完美填充了这些值.

为了获得更好的解决方案，请制作一个带有2个复选框和单选按钮的简单报告..从数据库中填充位值，并检查其是否以简单格式正确打印.
谢谢

are you converting your print to PDF?
If so please check with browser compatibility.

If not then you gotta check with the char values or int values of database, which you had set for the flag to be representd in (RadioButtons)RDBs. Please check whether the values are been populated perfectly from Backend.

For better solution, Please make a simple report with 2 check box and radiobuttons.. populate the bit values from the database and check whether its printing well in the simple format.
Thanks
