Hiow do I tell if printing was successful?

rbuser

I have an automated app that prints reports to designated
printers. I want it to run unattended. Is there a way to confirm
printing has been successful?

Hi Pat,

This really depends on what you consider a successful print. As far as
ReportBuilder is concerned, a successfull print is determined by the Windows
API calls to the driver are successful. RB however has no knowledge whether
the report was actually produced (i.e. out of paper perhaps). See the
following article on how to detect if the report was printed to the printer.
Idealy you should receive an exception if there is an error in RB when
printing.

Tech Tip: Detecting whether Report was
Printed to the Printer
------------------------------------------

The Report.AfterPrint event can be used to
determine whether the report was printed
to the printer (rather than preview, ...).


Example:


procedure TForm1.ppReport1AfterPrint(Sender: TObject);
begin

if (ppReport1.PrinterDevice <> nil) then
ShowMessage('Report was printed to the printer');

end;



Note: If the user cancels the report while it
is running, then the Report.OnCancel event will
fire, followed by the Report.AfterPrint event.

Example:

procedure TForm1.ppReport1Cancel(Sender: TObject);
begin
ShowMessage('Printing cancelled by user');

end;
