For a printing subsystem having access to a central library of electronically represented fonts, the ability to embed font identification (FONTID) within the text stream for the selection of fonts for use in printing has greatly enhanced composing printed pages. An added degree of flexibility occurs when a page-formatting control block enables a digital processor, controlling the printer, to substitute one font for a font indicated in the incoming text stream. This substitution is particularly useful for monospace fonts, and can be used for proportional space fonts when the width table of the substituting and substituted fonts exhibits predetermined identities. The incoming text stream is shown as having FONTID A and FONTID 4 embedded in a stream of text.
