  • System wide local copy management of screen copy printing
    Patent number: 5051926
    Abstract: With a 370 processing system, such as an IBM Entry Level System 9371, multiple IBM 3151 ASCII Display Stations can be attached with a plurality of I/O processors. A Local Copy Manager is provided for each of the I/O processors to execute. The microcode embodiment emulates a single 3274 Control Unit with a display station attached. Each I/O processor executes the unique Local Copy microcode and intercepts all print keys from each display station, captures the terminal's screen data, and interrupts the 370 processor with a request for service. There may be multiple printers defined. Printing of a hard copy of the screen is output of an operator defined printer demand.
