The configuration shown by the solid line is the processing on the printer device 9 side, and the configuration shown by the dotted line is the processing on the host computer 2 side. The operator of the host computer 2 inputs an instruction of “power on” from the keyboard 7 to the power on command issuing unit 4 according to a predetermined method. Then, the power-on command issuing unit 4 causes the communication control unit 3 to output a “power-on command” to the printer device 9 (step S100). Output "power-on instruction"
Is transmitted via the communication line 1 and is input to the main power supply control determination unit 11 via the communication control unit 10 of the printer device 9 (step S105).

When this "power-on command" is input, a permission state indicating whether power control is possible is obtained from the power control permission determination unit 18 to determine whether power can be turned on, and the state monitoring unit 16 An installation state indicating whether the installation state of the printer device 9 is normal or abnormal is obtained (step S1).
10). Here, the permission state and the installation state are determined (step S115). If the permission state indicates that the power control is possible and the installation state is normal, an instruction of “turn on the power” is output to the main power supply control unit 14. (Step S12
0).

At the same time, the fact that the power is turned on is output to the power status display function unit 12, and "power on" is displayed on the display unit 13 (step S125). Then, it responds to the host computer 2 via the communication control section 10 that the power has been turned on (step S130). The host computer 2 which has received this response notifies the printer status monitoring function unit 6 of the response, and the printer status monitoring function unit 6 causes the CRT 8 to display that the printer device 9 has been turned on. 9 is recognized (step S135).

FIG. 2 is a flowchart showing the contents of a power-off process executed when the main power-supply control determining unit 11 of the printer 9 inputs a "power-off command" from the host computer 2. Similarly, the configuration shown by a solid line is processing on the printer device 9 side, and the configuration shown by a dotted line is processing on the host computer 2 side. The operator of the host computer 2 inputs an instruction of “power cutoff” to the power cutoff command issuing unit 5 from the keyboard 7 according to a predetermined method. Then, the power-off command issuing unit 5 instructs the communication control unit 3 to issue a “power-off command” to the printer device 9.
Is output (step S200). The output “power-off command” is transmitted via the communication line 1 and is transmitted to the printer 9.
Is input to the main power control determining unit 11 via the communication control unit 10 (step S205).

The main power supply control section 11 transmits the "power supply cutoff command"
Is input, the power control permission determination unit 18 acquires a permission state indicating whether power control is possible, and the state monitoring unit 16 determines whether the installation state of the printer device 9 is normal. An installation state indicating whether the status is abnormal or whether a printing operation is being performed is acquired (step S210). Here, the permission state and the installation state are determined (step S215). If the permission state indicates that power control is possible and the installation state is normal and the printing operation is not being performed,
An instruction of “power off” is output to the main power control unit 14 (step S220).

At the same time, the fact that the power is turned off is output to the power status display function unit 12, and "power cut off" is displayed on the display unit 13 (step S225). Then, it responds to the host computer 2 via the communication control unit 10 that the power has been cut off (step S230). The host computer 2 that has received this response notifies the printer status monitoring function unit 6 of the response, and the printer status monitoring function unit 6 causes the CRT 8 to display that the power of the printer device 9 has been turned off, and prompts the operator to print the printer device. 9 is recognized (step S235).

If it is determined in step S215 that the power supply cannot be cut off, the power supply is not cut off. Then, it responds to the host computer 2 via the communication control unit 10 that the power cannot be turned off (step S230). The host computer 2 that has received the response notifies the printer status monitoring function unit 6 of the response, and the printer status monitoring function unit 6 displays on the CRT 8 that the power of the printer device 9 cannot be shut off, and prompts the operator to print the printer device 9. (Step S2)
35).

Therefore, the main power control determining unit 11 for executing the power-on processing and the power-off processing based on the above-mentioned input predetermined command comprises the instruction input means, the power control availability determination means, and the power control means. I do. In addition, since the power status of the printer 9 is displayed, the power status display function unit 12 and the display unit 13 constitute power status display means. Further, the printer status monitoring function unit 6 and the CRT 8 of the host computer 2 constitute status notification means.
