Пробую библиотеку TCPDF.Я хочу использовать TCPDF для динамического создания PDF-документов из базы данных MySQL с использованием PHP.Требуемое решение должно выглядеть следующим образом:
Pdf-решение 
На каждой странице должны быть напечатаны данные клиента, после того, как это будет сделано, перейдите на другую страницу дляследующий клиент, пока все они не будут распечатаны.
В приведенном ниже примере кода достигается печать сведений о клиенте на каждой странице, но я не могу понять, как напечатать итоги на каждой странице.
