У меня есть экран, на котором я загружаю значение из базы данных, затем загружаю контроллер для штрих-кода и генерирую изображение. Я хочу напечатать сгенерированное изображение штрих-кода.
Это контроллер штрих-кода
https://github.com/jahangiralammahi/codeigniter_barcode_master
Я считаю, что есть также возможность сохранить в файл .png и распечатать. Но тоже не получилось.
Так что любая помощь будет высоко ценится

return true;
}
</script>
У меня может быть вид печати последней строки штрих-кода, так что я думаю, что он захватывает последнюю использованную ссылку на идентификатор. Таким образом, любая кнопка печати, которую я нажимаю, получает тот же последний штрих-код.
