function PrintForm(AForm: TForm; ATag: Longint): integer;
{используйте: PrintForm(Form2, 0);
AForm - форма, которую необходимо напечатать. Если вы, к примеру,
печатаете Form2 из обработчика события Form1, то используйте Unit2
в списке используемых модулей в секции implementation молуля Unit1.
ATag - поле Tag компонента, который необходимо печатать или 0 для всех.
Если Tag компонента равен 14 (2+4+8), он буден напечатан в случае,
когда ATag равен 0, 2, 4 или 8.
Функция возвращает количество напечатанных компонентов. }
