Almost works, but prints a 2cm square form in the middle of the page. Really
needs to fill the page.
Cheers,
Dave.

Try this rountine. Just assign FormHandle to whatever form you are printing.
uses printers;
procedure TForm1.Button1Click(Sender: TObject);
var
FormHandle: THandle;
wDC: HDC;
SrcRect: TRect;
Bmp: TBitmap;
begin
Bmp := TBitmap.Create;
with Bmp do
try
FormHandle := Self.Handle;
SetForegroundWindow(FormHandle);
RedrawWindow(FormHandle, nil, 0, RDW_INVALIDATE+RDW_UPDATENOW);
GetWindowRect(FormHandle, SrcRect);
Width := SrcRect.Right-SrcRect.Left;
Height := SrcRect.Bottom-SrcRect.Top;
wDC := GetWindowDC(FormHandle);
BitBlt(Canvas.Handle, 0, 0, Width, Height, wDC, 0, 0, SRCCOPY);
with Printer do
begin
BeginDoc;
Canvas.Draw((PageWidth - Bmp.Width) div 2,
(PageHeight - Bmp.Height) div 2, Bmp);
EndDoc;
end;
finally
Bmp.Free;
end;
end;

Problem is, it is failing on all printers (lasers, plotters and inkjets), at
least one that has 80M of ram, and we use for GIS work, i.e very large
graphics.
Any ideas what to try to solve this?
Any other automated way to print the current form?
Dave.

One possability is that the form graphic is too much for the memory in the
printer. This may be a printer problem rather than a Delphi problem.
