A font is not analogous to a signifier. Rather it renders the signifier itself internally complex. It is a sub-element of the signifier. A computer font cannot be thought of, therefore, as a genetic element of the sign. In text for example, a font must be thought of independently from content, written markings, etc.
Fonts are indicative of what is known in the digital text as a protocol.
They regulate representation. The concept of zero-wait transfer governs contemporary ideas regarding textuality. In a digital network, much like previous types of value economies, information is produced in order to be exchanged or transferred. However, under digital transfer texts are exchanged according to an atemporal logic and through digital means. Immediation means both immediate and mediated.
