The dot matrix printer had a sheet feed for short documents and a tractor attachment for long reports on continuous stationery. This unit could print 90 characters per second at draft quality and 20 characters per second at higher quality, and could also produce graphics. However it had only 9 printing pins and even its higher quality did not match that of 24-pin printers. The dot matrix printer was not very robust as its chassis was made entirely of plastic. Users who needed to support higher print volumes or to produce graphics could buy a daisy-wheel printer or graph plotter from Amstrad. The daisy-wheel printer could not produce graphics.
