如何通过FoxitReaderOCX.ocx实现PDF文件无预览直接打印？

Absolutely, you can print PDFs directly without triggering the preview interface using FoxitReaderOCX.ocx—your current code is missing a key configuration step that tells the control to skip the preview/dialog. Here's how to fix it:

Solution 1: Use the PrintSilent Property #

Most versions of the Foxit OCX include a PrintSilent boolean property that disables both the preview window and print dialog. Just set this to True before calling PrintFile:

Private Sub Command1_Click()
    FoxitReaderOCX1.OpenFile ("C:\test_raport_PDF.pdf")
    ' Enable silent printing (no preview/dialog)
    FoxitReaderOCX1.PrintSilent = True
    FoxitReaderOCX1.PrintFile
End Sub

Solution 2: Configure Print Parameters with SetPrintParam #

If PrintSilent isn't available in your OCX version, use the SetPrintParam method to explicitly disable the print dialog (which also skips the preview):

Private Sub Command1_Click()
    FoxitReaderOCX1.OpenFile ("C:\test_raport_PDF.pdf")
    ' Disable print dialog/preview by setting "ShowDialog" to 0
    FoxitReaderOCX1.SetPrintParam "ShowDialog", "0"
    ' Optional: Specify a specific printer if needed
    ' FoxitReaderOCX1.SetPrintParam "PrinterName", "Your Default Printer Name"
    FoxitReaderOCX1.PrintFile
End Sub

Important Notes #

• Ensure you're using a compatible version of FoxitReaderOCX.ocx—older versions might not support these silent printing properties. Check the official Foxit OCX documentation for your specific version if you run into issues.
• Verify that the PDF file path is correct and the control has read access to the file.
• If you need to adjust other print settings (like page range, copies), you can add additional SetPrintParam calls (e.g., "Copies", "2" or "PageRange", "1-5").
