Graphical sheet technique for automatically changing the conditions of a printer/plotter

摘要

A technique for altering the operating conditions of a printer/plotter, which includes a laminar medium on which the coded marks are made in accordance with parameter values, an optical detector system for reading the laminar medium, a so-called acquisition system which picks up the signals from the optical system, and a microprocessor which can compare the coded values for the parameters with equivalence tables in order to provide the appropriate instructions to the printer/plotter components for changing the parameter settings.
