ABSTRACT:
A system for controlling and displaying the printing format of dot matrix printers includes a microprocessor, a memory which is loaded with programs from replaceable software cards, and a control panel having a plurality of control buttons, an aligned display, and a rotary control coupled to the microprocessor. In a first mode, depression of a selected control button accesses the corresponding one of the parameters of the most commonly used print parameters and repeated actuation of the selected control button cycles through the options contained within the parameter, the parameter and current option being sequentially presented on the display. In a second mode under microprocessor control, each one of the parameters in a printing parameter menu is sequentially accessed and rotation of the rotary dial provides scrolling through each option contained within the parameter. Sets of selected parameter options can be saved under specified designations for later retrieval and use. The rotary control is also independently used to move paper and printhead to starting positions. Thus a great number of parameters, with a number of options for each parameter can be selectively set by an operator in an exceptionally easy to understand and use manner.
