Abstract: A method of counting an actual usage time of each CPU in a computer system using a plurality of computers for distributed processing of jobs comprising first counting a CPU usage time used for each job, then counting a processing wait time in memory access of each CPU whenever executing each job, subtracting the processing wait time of each CPU from the CPU usage time for every job, and setting the thus calculated corrected CPU usage time as the actual CPU usage time. A job control system has a means for realizing this method and uses the CPU usage time and the corrected CPU usage time obtained by this means to control the jobs and charge the users.

Abstract: The present invention provides a method and an apparatus for driving and controlling a thermal head used in a printing device, such as a tape printer, in response to the temperature variations of the printing device environment and the thermal head. According to the present invention, in the printing operation of the tape printer, measurements are made of the initial temperature T1 immediately after the power is switched on, the temperature prior to printing T2, and the ambient temperature of the thermal head each time the thermal head prints T3 (i). If the temperature difference between the initial temperature T1 and the temperature prior to printing T2 is small, the duration of the current signals provided to the thermal head is controlled in accordance with the temperature prior to printing T2, which is the most recently measured thermal head ambient temperature best reflecting the printing device environmental temperature.
