Apple ImageWriter I

The ImageWriter dot matrix printer was introduced in 1984, and it was used at UBC during the mid- to late 1980s. Designed specifically to complement Apple's new Macintosh computer, it contained custom Apple-made firmware that worked with the Macintosh to allow WYSIWYG-like graphical printing capabilities, which couldn’t be found in other printers at the time.
