Printing with different printer

Hi,

 It seem that printing with different printer result in some problem with the font. I was using a Canon Bj-200e and i didnt have the problem with the font but i change the printer for a HP DeskJet 920c and the font output is weird.

 I use the font "ARIAL" but the output of the HP is printing some kind of fixed font (each caracter have the same length) so the text take more space.

Is this in my rpogram the problem or the HP dont support "ARIAL" font??

Here the code i use before BeginDoc

 Printer.PrinterIndex := -1;    
 Printer.Title := 'BDM';  
 Printer.Orientation := poPortrait;

 H1mm := GetDeviceCaps(Printer.Handle, LogPixelsX) / 25.4;
 V1mm := GetDeviceCaps(Printer.Handle, LogPixelsY) / 25.4;

 Printer.Canvas.Font.PixelsPerInch := GetDeviceCaps  (Printer.Handle, LogPixelsX);

 Printer.BeginDoc;
 with Printer.Canvas
  do
   begin
    Brush.Color := clWhite;
    Brush.Style := bsClear;

    Font.Name := 'Arial';
    Font.Size := 20;
    Font.Style := [fsBold];
    Font.Pitch := fpFixed;
    TextOut(trunc(MidX - (TextWidth('XYZ') / 2)),
            TopY + trunc(1 * V1mm),'XYZ');

If you can help me, i would appreciate it.

Thanks

According to HP's website this printer doesn't support Arial fonts directly. Note:

http://www.hp.com/cposupport/printers/support_doc/bpd08808.html#P162_5153


-Also, there seems to be a lot of driver updates for all of their models. You might want to check that you have the latest and greatest.



Good luck.

Hi,

 I forget to write this in the previous comment.

 If ARIAL font is not supported, how a program like MS-Word can print the font???

Thanks

To answer both of your questions at once:

I believe that what Word does is to print to an offscreen bitmap first and then draw that bitmap on the printer canvas as opposed to drawing directly on the printer canvas. This way it makes no difference if a particular font is not supported by the printer. As long as the O/S supports it, you're printing. Now, as to what can/should you do to make your application portable to any machine:

See above! <g>


Good luck!!

Sure..off the top of my head:

var BMP:TBitmap;
begin
  BMP:=TBitmap.create;
  With Bmp do
  begin
   Width:=PageWidth;
   {use printer.canvas.Cliprect.right or getdevicecaps for this}
   Height:=PageHeight;
   {See above}
    with canvas do
    begin
     Brush.Color := clWhite;
     Brush.Style := bsClear;
     Font.Name := 'Arial';
     Font.Size := 20;
     Font.Style := [fsBold];
     Font.Pitch := fpFixed;
     TextOut(trunc(MidX - (TextWidth('XYZ') / 2)),
           TopY + trunc(1 * V1mm),'XYZ');
 
    end;
  end;
  Printer.BeginDoc;
  Printer.Canvas.Draw(0,0,bmp);
  Printer.EndDoc;
  FreeAndNil(bmp);  
end;

Good luck!!

I print using Arial fonts all the time on a variety of printers and I'm quite sure it doesn't revert to some other font.  Windows takes care of all that.

I think there is a problem here:

  Font.Pitch := fpFixed;

I think that should read:

  Font.Pitch := fpVariable;

In fact, I don't set Font.Pitch at all.

Hi
  You were right Mike, that was the problem. It seem the canon driver dont care about Pitch but HP does.

Thanks for your help both of you.
