ABSTRACT:
An arrangement for effecting a variable modification of information used to control a printer unit of a teleprinter has a first store containing information for basic functions required to control the printer unit. A first decoding circuit analyzes received teleprinter characters and drives the first store. A second store contains information required to modify the basic functions. A second decoding circuit analyzes the count reached by a counter and drives the second store. A setting up matrix is sampled by the counter and feeds its output via a multiplexing circuit to a comparator device. The comparator device compares the result of a sampling of the setting up matrix and a read out from the second store with the received teleprinter character, and, if the result is positive, the comparator device causes information contained in the second store to be combined with information from the first store to create a modified information feed to the printer unit.
