Printing Error

I try to print with something like this:

Var
prn:TPrinter;
begin
Prn.BeginDoc;
prn.canvas.draw(10,10,Image1.Picture.Graphic);
prn.EndDoc;
end;

or like this:

Var
prn:TPrinter;
begin
prn:=TPrinter.Create;
Prn.BeginDoc;
prn.canvas.draw(10,10,Image1.Picture.Graphic);
prn.EndDoc;
prn.Free;
end;

but it stops with access violation error. I tried to trace the problematic line(by commenting all text except one line each time) and found that the prn.BeginDoc; causes the AV error in both cases.

please help!

Hi...

Make sure that you've added the printers unit to your uses clause above.

uses
  Printers;

try this

Printer.BeginDoc;
 ....
   .... (your text here)
      .....
Printer.EndDoc;

don't declare prn as type TPrinter.

Regards
Tazi
