WEB сахифани HTML бошқарув ёрдамида чоп этиш
HTML бошқарувнинг иккита усулидан фойдаланиш мумкин. Булар - AutoPrint ёки PrintPage.
AutoPrint ёрдамида чоп этишга мисол қуйида кўрсатилган.
uses
Printers;
procedure TForm1.Button1Click(Sender: TObject);
var
OldCur: TCursor;
begin
OldCur := Screen.Cursor;
with Printer do
begin
BeginDoc;
HTML1.AutoPrint(handle);
Title := HTML1.URL;
EndDoc;
end;
Screen.Cursor := OldCur;
end;
