Hi.

I found a problem in TCairoPsCanvas integration process. In TCairoPsCanvas.BeginDoc I nedd to know OutputFileName (1), but this is inicialized later in TCUPSPrinter.DoBeginDoc (2).

procedure TPrinter.BeginDoc;
begin
  ...
  if not FRawMode then begin
    Canvas.Refresh;
    TPrinterCanvas(Canvas).BeginDoc; //<-- 1
  end;
  //Call the specifique Begindoc
  DoBeginDoc;  //<-- 2
  ...
end;

I think, that logically sould be printer started (DoBeginDoc) before call Canvas.BeginDoc. Thus I would like to swap calling order:

procedure TPrinter.BeginDoc;
begin
  ...
  //Call the specifique Begindoc
  DoBeginDoc;
  if not FRawMode then begin
    Canvas.Refresh;
    TPrinterCanvas(Canvas).BeginDoc;
  end;
  ...
end;

But I do not know if it will not cause some problems in other printer implementations.

If order swaping will be refused, I have another but dirty solution.
