在 c# 中使用订书钉打印 PDF

Question

我正在尝试使用 c# 以编程方式打印 pdf。我尝试了不同的库（PostSharp、PDFium 等）以及 adobe SDK。但是，我找不到任何有关打印和装订打印输出的信息。

我尝试使用 PrintTicket 对象 (Microsoft) 来设置 Stapling 属性，但它不起作用。我已确认我安装了正确的打印驱动程序。我可以在手动打印时装订打印输出，所以我确定打印机支持它。

我编辑了帖子以包含完整的代码。我在这里使用的 PDF 库是 PdfiumViewer。我没有检查这段代码中的返回值，但如果我运行它，我得到的返回值会给我“ConflictStatus.ConflictResolved”。

        using (var server = new PrintServer("print server name"))
        {
            var printerName = "printer with stapling capabilities name";
            var queues = server.GetPrintQueues();
            using (var queue = queues.FirstOrDefault(x => x.FullName == printerName))
            {
                var printTicket = queue.DefaultPrintTicket;
                printTicket.Collation = Collation.Collated;
                printTicket.Stapling = Stapling.StapleTopLeft;
                queue.UserPrintTicket = printTicket;
                queue.CurrentJobSettings.CurrentPrintTicket = printTicket;
                var ret = queue.MergeAndValidatePrintTicket(queue.UserPrintTicket, printTicket);
                using (var pdfDoc = PdfDocument.Load("path to pdf"))
                {
                    using (var printDoc = pdfDoc.CreatePrintDocument())
                    {
                        printDoc.PrinterSettings.PrinterName = printerName;
                        printDoc.PrinterSettings.ToPage = 2;
                        printDoc.Print();
                    }
                }
            }
        }

我终于找到了有用的东西！我从以下获得代码：https://www.codeproject.com/Articles/488737/Storing-and-recalling-printer-settings-in-Csharp-n

public static class PrinterUtilities
{
    [DllImport("kernel32.dll", ExactSpelling = true)]
    private static extern IntPtr GlobalFree(IntPtr handle);

    [DllImport("kernel32.dll", ExactSpelling = true)]
    private static extern IntPtr GlobalLock(IntPtr handle);

    [DllImport("kernel32.dll", ExactSpelling = true)]
    private static extern IntPtr GlobalUnlock(IntPtr handle);


    /// <summary>
    /// Grabs the data in arraylist and chucks it back into memory "Crank the suckers out"
    /// </summary>
    /// <param name="printerSettings"></param>
    /// <param name="filename"></param>
    public static void SetDevModeFromFile(PrinterSettings printerSettings, string filename)
    {
        IntPtr hDevMode = IntPtr.Zero;// a handle to our current DEVMODE
        IntPtr pDevMode = IntPtr.Zero;// a pointer to our current DEVMODE
        try
        {
            // Obtain the current DEVMODE position in memory
            hDevMode = printerSettings.GetHdevmode(printerSettings.DefaultPageSettings);

            // Obtain a lock on the handle and get an actual pointer so Windows won't move
            // it around while we're futzing with it
            pDevMode = GlobalLock(hDevMode);

            // Overwrite our current DEVMODE in memory with the one we saved.
            // They should be the same size since we haven't like upgraded the OS
            // or anything.


            var fs = new FileStream(filename, FileMode.Open, FileAccess.Read);
            var temparray = new byte[fs.Length];
            fs.Read(temparray, 0, temparray.Length);
            fs.Close();
            fs.Dispose();
            for (int i = 0; i < temparray.Length; ++i)
            {
                Marshal.WriteByte(pDevMode, i, temparray[i]);
            }
            // We're done futzing
            GlobalUnlock(hDevMode);

            // Tell our printer settings to use the one we just overwrote
            printerSettings.SetHdevmode(hDevMode);
            printerSettings.DefaultPageSettings.SetHdevmode(hDevMode);

            // It's copied to our printer settings, so we can free the OS-level one
            GlobalFree(hDevMode);
        }
        catch (Exception)
        {
            if (hDevMode != IntPtr.Zero)
            {
                GlobalUnlock(hDevMode);
                // And to boot, we don't need that DEVMODE anymore, either
                GlobalFree(hDevMode);
                hDevMode = IntPtr.Zero;
            }
        }

    }
}

然后在我的主类中调用它

    private static void PrintTest()
    {
        using (var pdfDoc = PdfDocument.Load("pdf doc path"))
        {
            using (var printDoc = pdfDoc.CreatePrintDocument())
            {
                var currentSettings = printDoc.PrinterSettings;
                SetDevModeFromFile(currentSettings, "bin file that has printer settings path");
                currentSettings.ToPage = 3;
                printDoc.Print();
            }
        }
    }

要使用上面的代码，我必须从链接下载原始解决方案。然后我运行原始解决方案，以便从打印机对话框更新装订/装订设置，然后将设置保存到“bin”文件。问题似乎是并非所有设置都由 .net 公开（可能是因为这些是更多特定于打印机硬件的设置）。要打开 pdf 文件，我使用了PDFiumViewer。我希望这对其他人有帮助。
