Printing Multipage PDF problems

[absoffthewake]

Hello there,

I'm having some major issues with printing PDF's. I've already spent at least 5 hours looking for a way to make this work, and am extremely frustrated. Basically, what I'm doing is initially loading the PDF at 72 dpi (PdfDpiRendering = 72). I'm doing this for speed.

Code: Select all

oGdViewer.PdfDpiRendering = 72
oGdViewer.DisplayFromPdfFile (Me.TxtFilepath)


If the user decides to print the PDF, it changes the dpi to 300, then reloads the image, then prints.

Code: Select all

oGdViewer.PdfDpiRendering = 300
oGdViewer.DisplayFromPdfFile (Me.TxtFilepath)
oGdViewer.PrintSetFromToPage 1, oGdViewer.NumPages
oGdViewer.PrintImage


The problem is, it does absolutely nothing relating to printing 95% of the time. It reloads the image no problem, but it seems like it skips the print command. When it does decide to print (usually the first time I send the print command), it prints at the 72 dpi, so the print quality is terrible. If I take out the reload code, it still does not work. If I take out the PrintSetFromToPage command, it prints every time, but obviously only prints the 1st page. The only way I have gotten it to work is with this code:

Code: Select all

For i = 1 To oGdViewer.NumPages
oGdViewer.DisplayFrame (i)
oGdViewer.PrintImage
Next i


The problem with this code is that it separates it into multiple print jobs, and cycles through the pages on the viewer, making it extremely slow & inefficient to print. Printing 50 pages takes 20 minutes on my 40 page per minute laser.

What am I doing wrong??

What am I doing wrong??

Nothing, this behaviour was fixed into the last release.

Hi,

I just downloaded the latest version two nights ago and I'm encountering the same problems using almost identical code as above. Am I missing something or what? I am attempting to load and print multipage pdfs could range between 1 and 100 pages.

Any guidance would be greatly appreciated.

Cheers!

Hi,

Terribly sorry about leaving that information out.

It only prints the first page.

Here's the code;

autPDF is object Automation "GdPicturePro5.GdViewer"
autPDF>>SetLicenseNumber("xxxxxxxxxxxxxxxxxxxxxxxxxxx")

autPDF>>DisplayFromPdfFile("c:\users\ken\desktop\WD12brochure.pdf")

nNumPages is int = autPDF>>PageCount
Trace(nNumPages)
autPDF>>PrintSetFromToPage(1,nNumPages)
autPDF>>PrintImage()

Thanks,
ken

Hi,

Your problem probably come from your printer or something else...

Check your PDF has more one page, if yes, try with another multipage PDF.

Best regards,

Hi,

Tried several different mult-page pdf's with same result.

Also, oddly enough, it is not printing at all anymore. I have run it through debug and I'm hitting the line of code and have also tried using the autPDF>>PrintImageDialog() which does show a dialog properly, but nothing ever hits the printer.

Any suggestions.

Thanks,
Ken

Hi,

What you mean by "which does show a dialog properly"

What is the returned value of the PrintGetStat() method ? (call this method after the print process).

Best regards,

Loïc

Hi,

PrintGetStat() returns a 31

Also, it is returning the correct number of pages for the selected pdf.

Thanks,
Ken

OK thanks,

Could you try now to download the last minor released ? http://www.gdpicture.com/download.php

What's append now ?

Best regards,

Hi,

Still no print job and status returned is 8.

Again, the code I'm using is;

autPDF is object Automation "GdPicturePro5.GdViewer"
autPDF>>SetLicenseNumber("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")

//autPDF>>DisplayFromPdfFile("c:\users\ken\desktop\WD12brochure.pdf")
autPDF>>DisplayFromPdfFile("c:\pb_reports\0408_215759903.pdf")
autPDF>>PrintGetActivePrinter()


nNumPages is int = autPDF>>PageCount
Trace(nNumPages)
autPDF>>PrintSetFromToPage(1,nNumPages)
autPDF>>PrintImage()
Trace(autPDF>>PrintGetStat())

Thanks
Ken

Hi,

this mean that you have not enought memory to rasterize a page of the PDF.

What is the value you are using for the PdfDpiRendering property ?

Hi Loïc,

First.... U Da Man!

I explicitly set the pdf dpi to 150 and it is now working.

Thanks so much for your help.

Cheers!
