PRINTING APPARATUS HAVING AN AUTOMATIC STATUS BACK FUNCTION, AND METHOD FOR CONTROLLING SAME

摘要

The present invention relates to a printing apparatus having an automatic status back function, and to a method for controlling same. More particularly, the present invention relates to a technique which detects the status of the printing apparatus for every predetermined status detection cycle, stores the value of the changed status to an automatic status back buffer if the status value of the printing apparatus has changed, checks the automatic status back buffer for every predetermined automatic status back buffer check cycle, and transmits only the most recently changed status value to a host apparatus, to thereby reduce the transmission of unnecessary data to the host apparatus and to reduce data processing loads on the host apparatus.
