Invoke a specific printer to print C# WPF

c#, wpf

Solution

PrintServer must be instance using a computer or printer server device in UNC format (`\\resource`) not a printer name:

For example, if the name of your computer, in your domain, is KashifPC and you have configured a printer, called "Printer1", you can use:

//example code. no error handling.
PrintServer localPS = New PrintServer(@"\\KashifPC")
PrinterQueue printer1 = localPS.GetPrintQueue("Printer1") //v.BarPrinter???
PrintDialog printDialog = new PrintDialog();
printDialog.PrintQueue = printer1
//rest of code

Problem

I want to call a specific printer to print in my WPF application. I have three printer Suppose Printer1 for Bar bill Print Printer2 for Kitchen bill Print Printer3 for Guest bill Print printers name already saved in database, while printing I get a printer name from DB and want to print from specific printer, not defaul printer Here is my code ``` var v = new PrinterDAL().GetPrinterSettings(); try { System.Threading.Thread thread = new System.Threading.Thread(new System.Threading.ThreadStart( delegate() { gridPrint.Dispatcher.Invoke(DispatcherPriority.Normal, new Action( delegate() { PrintDialog printDialog = new PrintDialog(); printDialog.PrintQueue = new PrintQueue( new PrintServer(@"\\" + v.BarPrinter), ""); printDialog.PrintVisual(gridPrint, ""); this.Close(); } )); } )); thread.Start(); } catch (Exception ex) { Xceed.Wpf.Toolkit.MessageBox.Show(ex.Message, "", MessageBoxButton.OK, MessageBoxImage.Error); } ``` I get an exception from this code "An exception occurred while creating the PrintServer object. Win32 error: The printer name is invalid."
