1. 功能
供应商送货单要根据物料的最小包装数量和送货数量，确定批次，每个批次一个数量，每个批次一个标签。
标签打印的模板来回切换很麻烦，所以在打印或预览的时候，不再选择模板。
1. 逻辑
因为单据有多个套打模板，每次需要来回切换，所以通过通过插件实现打印，插件里调用打印服务，插件里重新构造打印数据。
2. 步骤
套打模板设计好标签；
BOS设计器在列表和表单里添加上空按钮；
列表插件和表单插件监听按钮的点击事件；
点击事件调用金蝶的打印服务；
重写OnPrepareNotePrintData事件，重构打印数据；
1. 开发
标签设计：打开套打设计器，没用数据表格，只是用布局表格和对应的文本，文本里绑定的动态字段；
添加按钮：。。。。
监听按钮的点击事件：
```C#
public override void BarItemClick(BarItemClickEventArgs e)
{
base.BarItemClick(e);
//if条件判断
if (e.BarItemKey.Equals("ZZY_LabelPreview"))
{
var formId = View.BusinessInfo.GetForm().Id;
var templateId = "cd0f5e24-8102-4530-9c4a-0160990d3c8";//供应商送货单
//这个方法获取当前表单所有的模板id，可以监听获取后，在代码里写死
//var templateIdDic= PrintServiceHelper.GetTemplatesByFormId(this.Context, View.BusinessInfo.GetForm().Id);
//获取FID
var fId = this.View.Model.DataObject["Id"].ToString();
//fId:打印单据id；templateId：套打模板id；formId：表单id，注意不能是扩展的表单，要是未扩展的表单id，上边有获取方法
var printJobs = Generateprintjobs(fId, templateId, formId); /生成打印job
var printJobKey=Guid.NewGuid().ToString();
this.View.Session[printJobKey] = printJobs;//任务放入session
NoteTemplateoperation(printJobKey,"Preview");
}
}
```
调用金蝶的打印服务：
这个是参考的大佬的帖子： [跳转过去，给他格赞](https://wenku.my7c.com/article/362702335958459648?productLineId=1&isKnowledge=2)
```C#
///<summary>生成打印任务</summary>
/// <param name="billId">单据内码</param>
/// <param name="templateId">套打模板标识</param>
/// <param name="formId”>业务对象标识</param>
private List<PrintJob> Generateprintjobs(string billid, string templateid, string formid) {
List<PrintJob> result = new List<PrintJob>();
PrintJob printJob = new PrintJob();
printJob.FormId = formid;
printJob.PrintJobItems = new List<PrintJobItem>();
printJob.PrintJobItems.Add(new PrintJobItem(billid, templateid));
result.Add(printJob);
return result;
}

public void NoteTemplateoperation(string printJobid, string printType, object printer = null) {
JSONObject jsonobj = new JSONObject();
jsonobj.Put("pageID", this.View.PageId);
jsonobj.Put("printJobId", printJobid);

重写OnPrepareNotePrintData事件：
每个动态字段要注册一下；
```C#
public override void OnPrepareNotePrintData(PreparePrintDataEventArgs e)
{
var metaData = FormMetaDataCache.GetCachedFormMetaData(this.Context, this.View.BillBusinessInfo.GetForm().Id);
if (e.NotePrintTplId == "cd0f5e24-8102-4530-9c4a-0160990d3c58")
{
DynamicObject billObj = this.Model.DataObject;
DynamicObject SupplierIdField = billObj["SupplierId"] as DynamicObject;
DynamicObject ConfirmerIdField = billObj["ConfirmerId"] as DynamicObject;
//动态字段注册赋值
DynamicObjectType dot = e.DataObjects[0].DynamicObjectType;// metaData.BusinessInfo.GetDynamicObjectType();
#region 注册动态字段
if (!dot.Properties.ContainsKey("QRCode"))
{
dot.RegisterSimpleProperty( "QRCode", typeof(object) );
}
if (!dot.Properties.ContainsKey("GoodsCode"))
{
dot.RegisterSimpleProperty("GoodsCode", typeof(object));
}
if (!dot.Properties.ContainsKey("GoodsName"))
{
dot.RegisterSimpleProperty("GoodsName", typeof(object));
}
if (!dot.Properties.ContainsKey("GoodsStandard"))
{
dot.RegisterSimpleProperty("GoodsStandard", typeof(object));
}
if (!dot.Properties.ContainsKey("SupplyName"))
{
dot.RegisterSimpleProperty("SupplyName", typeof(object));
}
if (!dot.Properties.ContainsKey("BanShu"))
{
dot.RegisterSimpleProperty("BanShu", typeof(object));
}
if (!dot.Properties.ContainsKey("SaleOrderCode"))
{
dot.RegisterSimpleProperty("SaleOrderCode", typeof(object));
}
if (!dot.Properties.ContainsKey("PurOrderCode"))
{
dot.RegisterSimpleProperty("PurOrderCode", typeof(object));
}
if (!dot.Properties.ContainsKey("Qty"))
{
dot.RegisterSimpleProperty("Qty", typeof(object));
}
if (!dot.Properties.ContainsKey("ProductDate"))
{
dot.RegisterSimpleProperty("ProductDate", typeof(object));
}
if (!dot.Properties.ContainsKey("ConfirmDate"))
{
dot.RegisterSimpleProperty("ConfirmDate", typeof(object));
}
if (!dot.Properties.ContainsKey("ConfirmUser"))
{
dot.RegisterSimpleProperty("ConfirmUser", typeof(object));
}
if (!dot.Properties.ContainsKey("ConfirmStatus"))
{
dot.RegisterSimpleProperty("ConfirmStatus", typeof(object));
}
if (!dot.Properties.ContainsKey("BillNo"))
{
dot.RegisterSimpleProperty("BillNo", typeof(object));
}
if (!dot.Properties.ContainsKey("BatchNo"))
{
