Generate pdf file fail

rbuser

I have a ppreport in a Isapi dll.

When i try to use print methode of ppreport i have this message
"Screen printer does not support printing. "

the printer is adobe pdf writer.

I have all my ppreport showdialog options to false

Can you help me to resolve this problem.

In debug mode all works fine.

If you are printing to a file, you should never receive this error. This
error is raised in the case which the report is being printed to the
printer, and there is no printer driver available. ReportBuilder has the
ability to use a virtual 'screen' printer. (See
Report.PrinterSetup.PrinterName in the object inspector).

This error is raised in RBuilder\Source\ppPrintr.pas. Search for the method
called TppCustomPrinter.GetDC. You will notice there is a check for
FPrinting. FPrinting is set to true when Printer.BeginDoc is called to a
start a print job for the printer.

Try running your code in a WebDebugger application so that you can trace it.

1. You need to set Report.DeviceType to the name of the PDF device that you
are using. At Delphi design-time, these names are listed in the
Report.DeviceType property editor drop down that is displayed by the object
inspector.

Exampe for Pragnaan PDF:

Report.DeviceType := 'Adobe Acrobat Document';


2. From looking at your code, I think you also need to set
Report.ShowCancelDialog to False.

thank you for your response
With WebDebugger all work fine.
I dont understand what appen with IIS.
The only difference is that my developpment machine is win NT and the IIS is
WINDOWS 2000 SERVER.
Do you know if is difference between this 2 systems.

Look my code is it correct ?
ppReport1.template.FileName := qualifyfilename('Etats\' + Etat +
'.rtm');
ppReport1.template.loadfromfile;
ppreport1.DeviceType := dtPrinter;
ppreport1.PrinterSetup.PrinterName :='SIRH';
ppReport1.PrinterSetup.DocumentName := Webcontext.Session.SessionID +
'_' + etat;
ppReport1.ShowPrintDialog := false;
ppReport1.print;

I don't use any addon. I only use RBUILDER and ppreport.
I have a PDF printer installed on my server (Acrobat writer). If i print
file on this printer this printer make a pdf file with the input file.
I have only 5 devices in devicetype propertie (archivefile,printer,screen,
xhtml,textfile)
i think the appropriate devicetype is printer.
this method work fine in debug mode.

thank for your time

When the Web application executes as an ISAPI .DLL under IIS, it will be
executing under a different user account.

There are two user accounts created by IIS: IUSR_MachineName and
IWAM_MachineName. (MachineName is replaced by the name of your computer).
The IWAM_MachineName account is a user account that IIS uses to run web
applications such as the web tier.

On the IIS server machine, you will need to install the acrobat printer
driver in such a way that it is available to the IWAM_MachineName account. I
think this requires that you log in to Windows as IWAM_MachineName and
install the printer driver.
