Hi,

Another option is to use TComPort.

Hi again :-)

I was forgetting! ^_^

You can try with Windows APIs using COM ports as files.
It should be possible for example to write something like
this:

uses SysUtils;

var T : TextFile;

begin
   AssignFile( T,'LPT1:' );
   Rewrite( T );
   write( T,'This is my printed text' );
   CloseFile( T );
end.

It should work with other ports too.

Please bear in mind that is UNTESTED.

HTH,

Andrew
