我尝试遵循基于Printing multiple document in c# window application
的代码当项目很少用于打印时，它会在热敏收据打印机上打印。但是，只要打印的项目显示超过1，就会花费无限循环。
这是我的代码
private void PrintReceipt()
{
//Assuming my Selector is 0
selector = 0;
printDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(printDocument1_PrintPage);
printDocument1.Print();
}
活动代码
void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
frmLogin fl = new frmLogin();
Graphics graphic = e.Graphics;
Font font = new Font("FontA11", 9.0f);
float fontHeight = font.GetHeight();
float pageWidth = e.PageSettings.PrintableArea.Width;
float pageHeight = e.PageSettings.PrintableArea.Height;
int startX = 52;
int startY = 10;
int offset = 40;

我不会在同一个程序中混合查询和打印指令...无论如何，当HasMorePages为true时，再次为下一页调用printDocument1_PrintPage并从头开始查询，这样你就可以了永远打印第一页。 在printDocument1_PrintPage中，您应该打印一般的第i页。因此，也许在第一页中，您将打印50行（表单1到50），然后使用成员变量，第二次调用该过程，您将从51到100继续打印，依此类推。因此，您需要在开始打印之前运行查询。
查看http://www.java2s.com/Tutorial/CSharp/0460__GUI-Windows-Forms/MultiPagePrint.htm，了解＆＃39;偏移＆＃39;在打印过程中总是递增，而不是每次都初始化（因此，您可以逐页打印所有文档）。
