dynamically redefinable character set (DRCS)
1. A feature of some printer controllers that allows the character set in use to be changed via commands in the data stream. The character sets invoked may be resident in the printer or may be downloaded via the interface.

2. A feature of many display terminals whereby the font may be redefined via the interface, allowing nonstandard character sets (e.g. Greek or Cyrillic) or special type fonts to be displayed. A hard copy of the display screen requires a compatible printer.
