Problems solved by technology

[0006] However, in the above-mentioned conventional wireless imaging device, it is not possible to flexibly change the established timeout value according to the communication state
Therefore, when the receiving sensitivity of the image data is lowered due to an obstacle in the wireless communication path, the printing operation is canceled, and thus the printing success rate is lowered.

Abstract

An imaging device capable of wirelessly receiving and transmitting data with an external device, having a wireless communication unit for receiving image data sent from the external device, demodulating the received image data, outputting the demodulated data, and detecting an image Wireless reception sensitivity of data, and output reception sensitivity information corresponding to the detection result. The apparatus further has an imaging unit for changing a timeout value based on the reception sensitivity information, and during transmission of data from the external device, when the time when data is not received exceeds the timeout value, stops receiving data from the external device. According to this wireless image forming apparatus, it is possible to improve the success rate of wireless printing even in the case where communication is interrupted due to increased communication path interference.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2002-53625 filed with the Korean Intellectual Property Office on September 5, 2002, the disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to a wireless imaging device of a wireless printing system and a method thereof, and in particular to a device for: changing a timeout value according to the receiving sensitivity of wirelessly transmitted data; and selecting stop and continuation of data based on the changed timeout value take over. Background technique [0003] A wireless printing system typically has a terminal, such as a PC, with a wireless communication unit, a wireless imaging device with the wireless communication unit, and an access point for relaying data input into each wireless communication unit, or Data output is relayed from each wireless communication unit. [0004] When no image data is input from the device within the e...
