I am testing the PDF Lib. I have been able to print PDFs from my code.

However, some PDFs just print a blank page while others print fine.

The problem PDFs open and print fine from Acrobat.

Not sure where to look.

Hi Bill,

without a relevant code snippet or a sample file (you can upload anywhere on a free file hoster) it's like looking into a glass bowl ;-)
A shot into the dark could be:
...
If QP.EncryptionStatus > 0 Then
QP.decrypt;
...
or
CombineContentStreams
or
NormalizePage

Cheers and welcome here,
Ingo

Here is the code.

It is called from a process which passes it the filename.

Clarion Ver 10 .

I am trying to find a sample I can post. ( Need one without Customer Info)

Thanks,

Bill

QuickPDF.CreateLibrary()

If QuickPDF.UnlockKey('----KEY----')

ST.Trace('>' & FileName & '<')

PDF:PDFFileName = Clip(Filename)

If Access:PDFFiles.Fetch(PDF:KeyPDFName) = Level:Benign THEN

ST.Trace('Found PDF')

Printer:SysID = PDF:PrintID

Access:Printers.Fetch(Printer:KeySysID)

END

St.Trace(Printer:PrinterName)

E# = QuickPDF.LoadFromFile(PDF:PDFFileName,'')

QuickPDF.NormalizePage(0)

St.Trace(E# & ' -- ' & PDF:PDFFileName)

Loc:CustomPrinter = QuickPDF.NewCustomPrinter(Printer:PrinterName)

QuickPDF.SetupCustomPrinter(Loc:CustomPrinter, 7, 1) ! Simplex

Loc:iPrintOptions = QuickPDF.PrintOptions(0, 0, '')

P# = QuickPDF.PrintDocument(Loc:CustomPrinter,1,QuickPDF.PageCount(),Loc:iPrintOptions)

St.Trace(P# & ' -- ' & PDF:PDFFileName)

QuickPDF.ReleaseLibrary()

Else

Message('Could not unlock library')

End

In the print dialog, there is a control labelled Comments & Forms.

If you have that set to Document or Document and Stamps, none of the forms fields will print at all (including constant form fields). If you select Form Fields Only, the form fields will print, but not anything else. To get everything to print, choose the Document and Markup option!!!

Based on the symptoms you describe, that should solve the problem (and turn off the print as image option which of course gives much inferior output).

Another way,maybe your pdf's size are too larger to print.I ever try to use a PDF Compressor -- https://www.imymac.com/free-imymac-pdf-compressor/" rel="nofollow - iMyMac PDF Compressor ,It is the best free PDF compressor software on Your Mac.

Ingo,

Thanks for the reply and welcome.

The PDFs are not Encrypted.

They are either a check image or simple text.

Neither CombineContentStatus or Normalize page work.

What would be the best way to get you a sample?

Which version of QuickPDF you're using?
If it's a very old version and on the other side the pdf uses the latest pdf specs...
How the security settings are set?

For upload a pdf you can use any (free) file hoster (like drop box for example) and post the download-link here.
