使用打印机名选择接口实现批量静默打印【SelectPrinterExt，P...

1、选择打印机名称：

private selectPrinterNameButtonClick(e){

        //参数 0:只返回选中的打印机名称，1：同时返回当前可用打印机列表，100：只返回当前可用的打印机列表

        this.View.AddAction("SelectPrinterExt",0)

}

protected override CustomEvents(e){

        //参数0 e.EventArgs：{"Data":"{\"Selected\":true,\"PrinterName\":\"Doro PDF Writer\" }","RetType":0}

        //参数1 e.EventArgs：{"Data":"{\"Selected\":true,\"PrinterName\":\"Doro PDF Writer\" ,\"AllPrinterNames\":[\"Microsoft XPS Document Writer\",\"Doro PDF Writer\"]}","RetType":1}

        //参数100 e.EventArgs：{"Data":"{\"Selected\":true ,\"AllPrinterNames\":[\"Microsoft XPS Document Writer\",\"Doro PDF Writer\"]}","RetType":100}

        var printNameObject =  e.EventArgs;

}

2、获取名称后调用打印进行静默打印；

/// <summary>

/// 打印

/// </summary>

/// <param name="printJobId">打印任务ID</param>

/// <param name="printType">打印类型</param>

/// <param name="printer">打印机ID</param>

public void NoteTemplateOperation(string printJobId, string printType, object printer = null, string printBarName = null)

{

    JSONObject jsonObj = new JSONObject();

    jsonObj.Put("pageID", this.View.PageId);

    jsonObj.Put("printJobId", printJobId);

    jsonObj.Put("action", printType);

    string action = string.Empty;

    if (printType.EqualsIgnoreCase("preview") || printType.EqualsIgnoreCase("PrintMergePreview"))

    {

        action = JSAction.printPreview;

        jsonObj.Put("printBarName", printBarName);

    }

    else if (printType.EqualsIgnoreCase("print") || printType.EqualsIgnoreCase("PrintMerge"))

    {

        action = JSAction.print;

        jsonObj.Put("printerAddress", printer.IsNullOrEmpty() == true ? string.Empty : Convert.ToString(printer));

    }

    this.View.AddAction(action, jsonObj);

}
