Courier
The most hated font in prepress. Courier was originally a face that was designed for the IBM Selectric typewriters. It is a typical fixed pitch design, monotone in weight and slab serif in concept. On computers, it is used to emulate typewriter output for reports, tabular work and technical documentation. Many output systems use Courier as a substitution font when fonts are missing in a document or on a system. This explains its ‘popularity’ in prepress.
