使用不同的打印机托盘打印PDF c#

有没有办法打印PDF并选择要以编程方式使用的纸盘?

我愿意接受诸如将PDF转换为其他格式并从那里打印的建议。

我可以使用PaperSource()打印到正确的纸盒,而PrintDocument()是否可以将PDF转换为这些功能可以理解的格式?

感谢。

基于从here on MSDN获取纸托PaperSource,如果您不介意使用Ghostscript.NET,这应该适合您:

public void PrintPdf(string filePath, string printQueueName, PaperSource paperTray)
{
    using (ManualResetEvent done = new ManualResetEvent(false))
    using (PrintDocument document = new PrintDocument())
    {
        document.DocumentName = "My PDF";
        document.PrinterSettings.PrinterName = printQueueName;
        document.DefaultPageSettings.PaperSize = new PaperSize("Letter", 850, 1100);
        document.DefaultPageSettings.PaperSource = paperTray;
        document.OriginAtMargins = false;

        using (var rasterizer = new GhostscriptRasterizer())
        {
            var lastInstalledVersion =
                GhostscriptVersionInfo.GetLastInstalledVersion(
                        GhostscriptLicense.GPL | GhostscriptLicense.AFPL,
                        GhostscriptLicense.GPL);

            rasterizer.Open(filePath, lastInstalledVersion, false);

            int xDpi = 96, yDpi = 96, pageNumber = 0;

            document.PrintPage += (o, p) =>
            {
                pageNumber++;
                p.Graphics.DrawImageUnscaledAndClipped(
                    rasterizer.GetPage(xDpi, yDpi, pageNumber),
                    new Rectangle(0, 0, 850, 1100));
                p.HasMorePages = pageNumber < rasterizer.PageCount;
            };

            document.EndPrint += (o, p) =>
            {
                done.Set();
            };

            document.Print();
            done.WaitOne();
        }
    }
}
