I coded it in Delphi 2007 because for some or other reason I couldn't get
the functionality I wanted with TPrinter, I think one of the things was to
send the name of the document to the printer so the customer could cancel
the specific page that was printing.
Anyway, I think it can be adjusted to suite whatever basic need, and yes,
it does not talk directly to the port but does in a sense bypass the
dreaded canvas and fonts!
Rename the object / class as needed!
