c#调用默认打印机打印和自己选择打印机打印的不一样，为什么？自己选的打印机打印出来是对的。

​ ​ ​ codesoft打印条码：


​ //获得所有打印机名称
Strings vars = lbl.PrinterSystem().Printers(enumKindOfPrinters.lppxAllPrinters);
//获得需要的打印机名称 打印机固定可直接给名称值
// string printName = vars.Item(2);
PrintDocument prtdoc = new PrintDocument();
string strDefaultPrinter = prtdoc.PrinterSettings.PrinterName;//获取默认的打印机名 ​ ​ ​

​

下面是自己选的打印机打印出来的。

要看你的打印代码，页面设置等等

你先把自己选的打印机设置成默认打印机,打印出来试试 再手动选择之前的默认打印机打印,打印 看看到底什么现象 怀疑你调用PrinterDialog.ShowDialog()之前,没有把当前的document传给控件,这样你从里面再取出document的时候,都变成默认设置了,你代码设置的都白设置了

整个代码如下： public void Print_KSIlabel(string printer, string Cus, string KSI_PO, string KSI_PN, string MFG_PN, string Box_Qty, string MFG, string COO, string COO2, string Pkg, string OF, string[] DC, string[] Lot, string[] Qty, string[] svsCode, string[] Addr, string Inner, string Outer, string KSI_IPM) { ApplicationClass lb = new ApplicationClass(); try { string a1 = System.Windows.Forms.Application.StartupPath + "\\KSIII.Lab"; lb.Documents.Open(@a1, false);// 调用设计好的label文件 lb.EnableEvents = true; lb.ActiveDocument.CopyToClipboard(); Document doc = lb.ActiveDocument; //选择合适的打印机 lb.Dialogs.Item(LabelManager2.enumDialogType.lppxPrinterSelectDialog).Show(); //给参数传值 doc.Variables.Item("Addr0").Value = Addr[0]; doc.Variables.Item("Addr1").Value = Addr[1]; doc.Variables.Item("Addr2").Value = Addr[2]; doc.Variables.Item("Addr3").Value = Addr[3]; doc.Variables.Item("Addr4").Value = Addr[4]; //以下是给条码上的变量赋值 doc.Variables.Item("KSI_PO2").Value = KSI_PO; doc.Variables.Item("MFG2").Value = MFG; doc.Variables.Item("KSI_IPM2").Value = KSI_IPM; doc.Variables.Item("KSI_PN2").Value = KSI_PN; doc.Variables.Item("MFG_PN2").Value = MFG_PN; doc.Variables.Item("COO2").Value = COO; doc.Variables.Item("Box_Qty2").Value = Box_Qty; doc.Variables.Item("DC02").Value = DC[0]; doc.Variables.Item("Lot02").Value = Lot[0]; doc.Variables.Item("Qty02").Value = Qty[0]; doc.Variables.Item("DC12").Value = DC[1]; doc.Variables.Item("Lot12").Value = Lot[1]; doc.Variables.Item("Qty12").Value = Qty[1]; doc.Variables.Item("DC22").Value = DC[2]; doc.Variables.Item("Lot22").Value = Lot[2]; doc.Variables.Item("Qty22").Value = Qty[2]; doc.Variables.Item("DC32").Value = DC[3]; doc.Variables.Item("Lot32").Value = Lot[3]; doc.Variables.Item("Qty32").Value = Qty[3]; doc.Variables.Item("DC42").Value = DC[4]; doc.Variables.Item("Lot42").Value = Lot[4]; doc.Variables.Item("Qty42").Value = Qty[4]; doc.Variables.Item("DC52").Value = DC[5]; doc.Variables.Item("Lot52").Value = Lot[5]; doc.Variables.Item("Qty52").Value = Qty[5]; //以下是给条码赋值 string l_K = "K" + KSI_PO, l_V = "V" + MFG, l_2P = "2P" + KSI_IPM, l_P = "P" + KSI_PN, l_1P = "1P" + MFG_PN, l_4L = "4L" + COO2, l_Q = "Q" + Box_Qty; doc.Variables.Item("KSI_PO").Value = l_K; doc.Variables.Item("MFG").Value = l_V; doc.Variables.Item("KSI_IPM").Value = l_2P; doc.Variables.Item("KSI_PN").Value = l_P; doc.Variables.Item("MFG_PN").Value = l_1P; doc.Variables.Item("COO").Value = l_4L; doc.Variables.Item("Box_Qty").Value = l_Q; doc.Variables.Item("PKG").Value = string.Format("{0:##0}", Convert.ToInt32(Pkg)); doc.Variables.Item("OF").Value = string.Format("{0:##0}", Convert.ToInt32(OF)); for(int i = 0; i<DC.Length; i++) { DC[i] = "9D" + DC[i]; } for (int i = 0; i < Lot.Length; i++) { Lot[i] = "1T" + Lot[i]; } for (int i = 0; i < Qty.Length; i++) { Qty[i] = "Q" + Qty[i]; } doc.Variables.Item("DC0").Value = DC[0]; doc.Variables.Item("Lot0").Value = Lot[0]; doc.Variables.Item("Qty0").Value = Qty[0]; doc.Variables.Item("svsCode0").Value = svsCode[0]; doc.Variables.Item("DC1").Value = DC[1]; doc.Variables.Item("Lot1").Value = Lot[1]; doc.Variables.Item("Qty1").Value = Qty[1]; doc.Variables.Item("svsCode1").Value = svsCode[1]; doc.Variables.Item("DC2").Value = DC[2]; doc.Variables.Item("Lot2").Value = Lot[2]; doc.Variables.Item("Qty2").Value = Qty[2]; doc.Variables.Item("svsCode2").Value = svsCode[2]; doc.Variables.Item("DC3").Value = DC[3]; doc.Variables.Item("Lot3").Value = Lot[3]; doc.Variables.Item("Qty3").Value = Qty[3]; doc.Variables.Item("svsCode3").Value = svsCode[3]; doc.Variables.Item("DC4").Value = DC[4]; doc.Variables.Item("Lot4").Value = Lot[4]; doc.Variables.Item("Qty4").Value = Qty[4]; doc.Variables.Item("svsCode4").Value = svsCode[4]; doc.Variables.Item("DC5").Value = DC[5]; doc.Variables.Item("Lot5").Value = Lot[5]; doc.Variables.Item("Qty5").Value = Qty[5]; doc.Variables.Item("svsCode5").Value = svsCode[5]; doc.PrintDocument();//打印 } catch (Exception err) { MessageBox.Show("列印错误:" + err.Message); return; } finally { lb.Quit();//退出 } }

大神，你有参考代码吗？能给我看看吗？

我没有页面设置的代码。
