ABSTRACT:
An error control system that allows the user to check the content of an error after the error has occurred and prevents the user from wasting paper. The system is designed for printers that continue to print when an error not requiring a stoppage of printing has occurred. When an error not requiring the printer to stop has occurred during printing, the content of an error is written into an error log, and the operation of printing subsequent pages continues. Thereafter, when the power supply of the printer is turned off and turned on again, the system checks whether or not data is present in the error log. If the data is present, the error data in the error log is printed out along with status data for the printer on a status sheet. The error log is cleared thereafter. Preferably, even if an error that does not require printing to stop occurs, if the accumulated number of occurrences of such error has risen to a predetermined value, the printer stops the printing operation temporarily and warns the user to eliminate the cause of the error.
