C#中打印拼接的字符串

实例化打印文档

//声明打印对象
PrintDocument pd = new PrintDocument();
int ilvPreviewIndex = 0; 

在打印事件中设置基本属性

private void btnPrint_Click(object sender, EventArgs e)
{
    //获取和设置标签的高宽和边距
    decimal dLabelHeight = nudLabelHeight.Value;
    decimal dLabelWidth = nudLabelWidth.Value;
    decimal dTopMargin = nudTopMargin.Value;
    decimal dLeftMargin = nudLeftMargin.Value;
    //设置边距
    Margins margin = new Margins(0, 0, 0, 0);
    pd.DefaultPageSettings.Margins = margin;
    pd.DefaultPageSettings.Margins = margin;
    //横向打印
    //pd.DefaultPageSettings.Landscape = true;
    //循环打印
    for(; ilvPreviewIndex < dgvPreview.Rows.Count; ilvPreviewIndex++)
    {
        //页面尺寸
        pd.DefaultPageSettings.PaperSize = new PaperSize("Custom", Utility.GetPixelByWidth(dLabelWidth), Utility.GetPixelByWidth(dLabelHeight));
        pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
        pd.Print();
    }
}
