推荐答案

每页调用一次PrintPage（）事件，直到e.HasMorePages为false - 因此任何代码每个页面将执行一次。 您需要在此活动之外指定（并初始化）您的我已打印的内容，否则它将始终继续重置。 参见文章绝对新手的.NET打印指南 [ ^ ] The PrintPage() event is called once per page until the e.HasMorePages is false - therefore any code in that sub will be executed once per page. You need to specify (and initialise) your "what have I already printed" outside of this event otherwise it will always keep resetting.
