15" wide carriage
Apple Imagewriter printer, Model A9M0305. This is the Wide Carriage model of the popular original Imagewriter (or Imagewriter I) dot matrix printer. The wide carriage printers were popular for business use, as they can print large spreadsheets.
All complete printers have a crack in the clear plastic cover - some worse than others, and the removable rear paper cover may have separated into two pieces as shown in photo 7.
