调用Bartender打印标签

[hw123hdk]

在社区用这个代码打印标签，能打出来，就是出纸要等50秒左右才出纸，好慢，打印机是TSC-TT244pro，刚学C# 不太懂，已经琢磨好几天了，有没有好心人知道是什么原因.谢谢

namespace WinFormTest
{
public partial class Form1 : Form
{

BarTender.Application btapp;
BarTender.Format btformat;

public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
try
{
btapp = new BarTender.Application();
btformat = btapp.Formats.Open(@"D:\Users\amaris.ma\Desktop\opp\opp\G05_TRAY2.btw", false, "");
}
catch (Exception ex)
{
MessageBox.Show("加载BarTender实例失败！");
}
}

private void button1_Click(object sender, EventArgs e)
{
btformat.PrintSetup.NumberSerializedLabels = 1; //设置打印份数
btformat.SetNamedSubStringValue("SN", "123233");
btformat.PrintOut(true, false); //第二个参数设置是否跳出打印属性;
MessageBox.Show("oook");
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
btformat.Close(BarTender.BtSaveOptions.btDoNotSaveChanges); //退出时是否保存标签
btapp.Quit(BarTender.BtSaveOptions.btSaveChanges);//退出时同退退出BarTender进程
}


}
}
