Method of monitoring the status of a peripheral device, and a computer and network system
First Claim
1. A method of monitoring a status of a first peripheral device on a network having connected thereto a first computer and the first peripheral device, wherein the first computer:
- detects a power of the first peripheral device when the first peripheral device is turned on;
sends a process command to the first peripheral device for a first time after detecting the power of the first peripheral device has been turned on;
when the first time sending the process command causes the first peripheral device to perform an operation, initiates monitoring the status indicating an operating state of the first peripheral device.

Abstract
A network system enables monitoring the status of peripheral devices from computers without concentrating a load on the network. A specific device driver that runs on a specific computer connected to the network has an initialization command transmission unit that sends a first initialization command to the specific printer when a process command is sent to a specific printer, and an operating status monitoring unit that, after initialization based on the first initialization command is completed, monitors the operating status of the specific printer until the printer power turns off. Because the specific computer does not initialize and does not monitor the operating status of the specific printer until the computer sends a process command, concentrating a load on the network is avoided when the network system starts up.

9. A computer comprising:
-
a processor; a non-transitory computer-readable medium; and a device driver that controls driving a first peripheral device over a network, the device driver comprising; a startup status monitoring unit that detects a power of the first peripheral device when the first peripheral device is turned on; a decision unit that determines if a process command is a first process command sent to the first peripheral device when the process command to perform an operation is sent to the first peripheral device that is controlled by the device driver; and an operating status monitoring unit that, when the process command is the first process command, starts monitoring the operating status indicating the operating state of the first peripheral device until the power of the first peripheral device turns off. - View Dependent Claims (10, 11, 12, 13, 14)

15. A network system comprising:
-
a first computer; and a first peripheral device connected over a network to the first computer, wherein the first computer; detects a power of the first peripheral device when the first peripheral device is turned on; and when a process command causing the first peripheral device to perform an operation is first sent from the first computer, the first computer initiates monitoring an operating status indicating an operating state of the first peripheral device until the power of the first peripheral device turns off. - View Dependent Claims (16, 17)
