Printing device, diagnosing method for printing device, and diagnosing program for printing device
First Claim
1. A printer that uses one of a plurality of channels to perform wireless communication, characterized by comprising:
- turn-off message output means for outputting a turn-off message suggesting an operation for turning off a device emitting radio interference;
turn-on message output means for outputting a turn-on message suggesting an operation for turning on said device emitting the radio interference; and
channel condition output means for outputting information indicating the condition of each of said plurality of channels according to the result of comparison between receive electric field strength during the time period from a time at which said turn-off message is outputted to a time at which said turn-on message is outputted and receive electric field strength after said turn-on message is outputted.

Abstract
A printer that enables a determination whether a failure has occurred in a device during initialization or a radio wave condition is bad. Receive electric field strength during a time period from a time at which a turn-off message is outputted to a time at which turn-on message is outputted and receive electric field strength after the turn-on message is outputted are measured. The measurements are compared with each other and information indicating the condition of each of a plurality of channels is printed out according to the results of the comparison. A user can reference the printed information to determine whether a failure has occurred in a device or the radio wave condition is bad.
