I have a multi-page fax that I'm trying to print each page. The part where I load the images to ImagePrintDocument goes quickly; once it starts the DoPrint, each page takes about 20 seconds to render to the printer. A four-page fax image takes 80 seconds to render to the spooler for printing. This seems like a long time considering the horsepower of the machine I'm using, the fact that each page is a 1bpp fax image, and how fast other operations are running. Here's the code snippet: Code: Dim printDoc As New ImagePrintDocument
printDoc.PrintOptions.ImageAutoRotate = True
printDoc.PrintOptions.PlaceholderAutoRotate = True
printDoc.DefaultPageSettings.Margins.Left = 25
printDoc.DefaultPageSettings.Margins.Top = 25
printDoc.DefaultPageSettings.Margins.Right = 25
printDoc.DefaultPageSettings.Margins.Bottom = 25
If MaxPageNumber > 1 Then
Dim images As New ArrayList
For i As Integer = 0 To MaxPageNumber - 1
Dim thisFrame As TiffFrame = CType(reader.LoadFrame(i), TiffFrame)
Dim newBitmap As New Aurigma.GraphicsMill.Bitmap
thisFrame.GetBitmap(newBitmap)
thisFrame.Dispose()
images.Add(newBitmap)
Next
printDoc.Source = images.GetEnumerator()
printDoc.PlacementMode = PlacementMode.MultipleImages
Else
printDoc.Source = imgViewer.Bitmap
printDoc.PlacementMode = PlacementMode.SingleImage
End If
printDoc.Print()
Why is this so slow? Edited by user Tuesday, December 18, 2007 8:13:22 PM(UTC)

Hello, Which printer resolution do you use? Try to decrease it in printer settings. |
