Title: Error print setting method, error print setting device, and storage medium
Inventor: KADOTA MASATOSHI
IPC: G06F3/0484
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To automatically make an error print by a printer only when a personal computer can not make an error display. SOLUTION: Once a user indicates a print process, it is judged whether a status monitor for displaying the status of a laser printer is set to display mode (S1080) and when the status monitor is set to the display mode, an error print mode is turned off (S1100). If an error occurs in the laser printer, error information is displayed on the screen of the personal computer and the laser printer does not print error information.
