PBytes = Marshal.StringToCoTaskMemAnsi(szString) The Celsius temperature is printed with a width of 6 positions and a precision of 3 positions after the decimal point. Assume that the printer is expecting ANSI text, and then convert How many characters are in the string?ĭwCount = (szString.Length + 1) * Marshal.SystemMaxDBCSCharSize Public static bool SendStringToPrinter(string szPrinterName, string szString)

Free the unmanaged memory that you allocated earlier. By using DOS2USB you can print directly from DOS to USB printer, Network Printer or any kind of printer.

Send the unmanaged bytes to the printer.īSuccess = SendBytesToPrinter(szPrinterName, pUnmanagedBytes, nLength) DOS2USB Supports any PC running Windows 2000, XP, VISTA, 7, 8, 8.1 and Windows Server 2003 (Service Pack 2), 2008, 2012 With LAN and RDP (Terminal Service) for Capturing Print and Redirection. Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength) Copy the managed byte array into the unmanaged array. Windows also has three file extensions you can save the file: Printer Files (. PUnmanagedBytes = Marshal.AllocCoTaskMem(nLength) Allocate some unmanaged memory for those bytes. or use the net use command to share the printer to an LPT device and then send the print job to that LPT device with the print /d:LPT1 path\to\file.

Read the contents of the file into the array. If the printer is the default you can do start /min notepad /p To run the example, create a new Windows Forms project and paste the example code into the form, replacing the file contents. When the function is given a printer name and an unmanaged array The following code example prints the file named C:\My Documents\MyFile.txt on the default printer. Public static extern bool WritePrinter(IntPtr hPrinter, IntPtr pBytes, Int32 dwCount, out Int32 dwWritten) Public static extern bool EndPagePrinter(IntPtr hPrinter) Public static extern bool StartPagePrinter(IntPtr hPrinter) Public static extern bool EndDocPrinter(IntPtr hPrinter) Public static extern bool StartDocPrinter(IntPtr hPrinter, Int32 level, DOCINFOA di) Public static extern bool ClosePrinter(IntPtr hPrinter) Public static extern bool OpenPrinter( string szPrinter, out IntPtr hPrinter, IntPtr pd) String command = "^XA^FO10,10,^AO,30,20^FDFDTesting^FS^FO10,30^BY3^BCN,100,Y,N,N^FDTesting^FS^XZ" ĭoc.PrinterSettings = new PrinterSettings() ĭoc.PrinterSettings.PrinterName = command) I used the following logic but it did not work.#HOW TO PRINT .PRN FILE USING C%23 CODE#
