Принтеры APPLE ImageWriter

APPLE ImageWriter

В дополнение к компьютерам Macintosh, в 1984 году Apple представила 9 игольчатый матричный принтер ImageWriter. Данная модель была способна создавать изображения, а также текст с разрешением до 144 точек на дюйм. Скорость печати данной серии составляла около 120 CPS. Рассматриваемая модель способна поддерживать Microsoft Windows на основе ПК с помощью включенного совместимого драйвера С. Ito 8510. Еще одной особенностью предлагаемых устройств была встроенная система самотестирования, активируемая удерживанием кнопки подачи во время включения принтера.

Спустя год Apple пересмотрела дизайн ImageWriter и выпустила принтер ImageWriter II. Данные устройства отличались прочностью, сравнительной экономичностью и были очень популярны среди пользователей. Они имели несколько дополнений, в том числе: подключаемый модуль сетевой карты, карту буферной памяти. Так же они поддерживали цветную печать с соответствующей лентой.

Как и его предшественник, принтер Apple ImageWriter II использовал 9-контактный C. Ito механизм, однако, был значительно быстрее, и имел скорость печати 250 CPS. Возможность печати цветных изображений и графики обеспечивалась использованием цветной ленты. Данная особенность аппарата была поддержана оригинальной версией QuickDraw на Macintosh. Несмотря на то, что принтер работает на монохромной платформе, он поддерживает выход на восемь цветов. С помощью ImageWriter II возможно распечатать цветные фото с сотнями вариантами цветов и полутонов. Рассматриваемый аппарат включает в себя три режима качества текста: NLQ в режиме 45 CPS – самое высокое качество печи текста; режим на 180 CPS на платформе Macintosh обеспечивает среднее качество текста; режим на 250 CPS, обеспечивает самую высокую скорость производства но низкое качество текста.

Данная модель выпускалась компанией Apple вплоть до 1996 года.

27-контактный матричный принтер Apple ImageWriter LQ ( L Эттер Q uality ) был введен в эксплуатацию в 1987 году. Качество печати было сравнимо с конкурирующими 24-контактными матричными принтерами, а разрешение составляло 320 × 216 точек на дюйм. В отличие от ImageWriter II, модель LQ была шумной и ненадежной. Установленная в принтере модели LQ печатающая головка была склонна к перегреву при больших объемах печати, а это способствовало расплавлению клея держащего кристалл, который в свою очередь поддерживал контакты.

В декабре 1990 года компания прекратила выпуск серии устройств APPLE ImageWriter. В то же время и прекратился выпуск оригинальных расходных материалов к данной серии устройств Apple.
