ABSTRACT:
After a laser printer has been inactive for a long period of time, the CPU in the laser printer compares the remaining toner status determined based on a detection by a toner sensor during a warm-up operation prior for performing a printing operation and the last remaining toner status that was determined during a printing operation and that is stored in memory, and displays the larger of the two.
