如何使用 C# 静默打印 .docx

Question

我想以静默方式打印 .docx 文件，并能够选择打印机的纸盘。

起初我尝试使用Microsoft.Office.Interop.Word打印 .docx但 Word 正在打开...

在我将 .docx 文件转换为图像并使用 ProcessStartInfo 打印它后，它向用户显示了一个打印窗口。

ProcessStartInfo info = new ProcessStartInfo(imageFilePath);

            info.Verb = "Print";
            info.CreateNoWindow = true;
            info.WindowStyle = ProcessWindowStyle.Hidden;
            Process.Start(info);

我尝试了另一种方法，它以静默方式打印图像，但图像模糊且缩放不正确。

            PrinterSettings settings = new PrinterSettings();
            string defaultPrinter = settings.PrinterName;

            FileInfo fileInfo = new FileInfo(imageFilePath);


            PrintDocument pd = new PrintDocument();
            pd.DocumentName = fileInfo.Name;

            pd.PrintPage += (sender, args) =>
            {
                Image i = Image.FromFile(imageFilePath);
                PrintPageEventArgs arguments = args;


                System.Drawing.Rectangle m = new System.Drawing.Rectangle()
                {
                    Y = 0,
                    X = 0,
                    Location = new System.Drawing.Point(0, 0),
                    Height = args.MarginBounds.Height,
                    Size = args.MarginBounds.Size,
                    Width = args.MarginBounds.Width
                };



                if ((double)i.Width / (double)i.Height > (double)m.Width / (double)m.Height)
                {
                    m.Height = (int)((double)i.Height / (double)i.Width * (double)m.Width);
                }
                else
                {
                    m.Width = (int)((double)i.Width / (double)i.Height * (double)m.Height);
                }
                args.Graphics.DrawImage(i, m);
            };

            pd.Print();

那么是否可以静默打印 .docx 并能够选择打印机的托盘？

有没有人遇到同样的问题。在这方面有任何帮助。提前致谢。

我找到了一个无法静默打印 .docx 的解决方案，因此我之前将其转换为 .png 图像。

将 .docx 转换为 .png 的链接

这是打印图像的代码：

            PrinterSettings settings = new PrinterSettings();
            string PrinterName = settings.PrinterName;

            //set paper size
            PaperSize oPS = new PaperSize
            {
                RawKind = (int)PaperKind.A4
            };
            //choose the tray here
            PaperSource oPSource = new PaperSource
            {
                RawKind = (int)PaperSourceKind.Upper
            };
            PrintDocument printDoc = new PrintDocument
            {
                PrinterSettings = settings,
            };
            //set printer name here it's the default printer
            printDoc.PrinterSettings.PrinterName = PrinterName;
            printDoc.DefaultPageSettings.PaperSize = oPS;
            printDoc.DefaultPageSettings.PaperSource = oPSource;

            printDoc.PrintPage += new PrintPageEventHandler((sender, args) =>
            {
                System.Drawing.Image img = System.Drawing.Image.FromFile(imageFilePath);
                int printHeight = (int)printDoc.DefaultPageSettings.PrintableArea.Height;
                int printWidth = (int)printDoc.DefaultPageSettings.PrintableArea.Width;
                int leftMargin = 0;
                int rightMargin = 0;

                args.Graphics.DrawImage(img, new System.Drawing.Rectangle(leftMargin, rightMargin, printWidth, printHeight));
            });

            printDoc.Print();
            printDoc.Dispose();
