Delphi-PRAXiS - Delphi Drucken?

Zum Memo:

To print the contents of a memo component:

1. Assign a text-file variable to the printer by calling AssignPrn.
2. Create and open the output file by calling Rewrite.
Any Write or Writeln statements sent to the file variable are then written on the Canvas of the printer object.

The AssignPrn procedure is declared in the Printers unit, so you must add Printers to the uses clause of the unit that calls AssignPrn.

When the printer is ready for input, you can write the contents (Lines property) of the memo to the printer.

oder:

he VCL TPrinter object encapsulates details of Windows printers. To get a list of installed and available printers, use the Printers property. The CLX TPrinter object is a paint device that paints on a printer. It generates postscript and sends that to lpr, lp, or another print command.
Both printer objects use a TCanvas (which is identical to the form's TCanvas) which means that anything that can be drawn on a form can be printed as well. To print an image, call the BeginDoc method followed by whatever canvas graphics you want to print (including text through the TextOut method) and send the job to the printer by calling the EndDoc method.

This example uses a button and a memo on a form. When the user clicks the button, the content of the memo is printed with a 200-pixel border around the page.
To run this example successfully, add Printers to your uses clause.

Delphi-Quellcode:

			procedure TForm1.Button1Click(Sender: TObject);

var

  r: TRect;

  i: Integer;

begin

  with Printer do

    begin

      r := Rect(200,200,(Pagewidth - 200),(PageHeight - 200));

      BeginDoc;

      for i := 0 to Memo1.Lines.Count do

       Canvas.TextOut(200,200 + (i *

Canvas.TextHeight(Memo1.Lines.Strings[i])),

                                   Memo1.Lines.Strings[i]);

      Canvas.Brush.Color := clBlack;

      Canvas.FrameRect(r);

      EndDoc;

    end;

end;

nimm ein RichEdit, das kann man per "RichEdit1.Print" drucken...
