Method of individually characterising a sequence of control signals

摘要

the method involves using two types of signals, one for controlling a machine, esp. a printing machine, and another for controlling an output unit, esp. a display or printer. The control signals are generated from stored control code by a processing unit so that machine-related information are displayed using the second type of control signals. The image code of an individual digital image is stored in the control code. When the machine information is output the digital image is composed from the image code and is at least partially output with the machine information. The processing unit periodically checks for the presence of image code in the control code; if the image code is not fully present the generation of control signals of the first and/or second type is stopped An Independent claim is also included for a method of controlling a machine, esp. a printer
