Several people have experienced problems with printing a QuickReport to a non-default printer.
Another issue is printing of selected pages.
QuSoft saw this and added a function PrinterSetup() which works properly with their model (other than my own TPrintDialog instances).
The following code shows how to print the current page or selected pages.
// ...
theReport : TQuickRep;
ReportPreview: TQRPreview;
// ...
begin
// print one page..
with theReport do
begin
PrinterSettings.FirstPage := theReport.PageNumber;
PrinterSettings.LastPage := theReport.PageNumber;
ReportPreview.QRPRinter.Print;
end;
end;
