Wireless image forming apparatus and method thereof
First Claim
1. A wireless image forming apparatus to wirelessly transmit and receive data with an external apparatus, comprising:
- a wireless communication unit to receive image data transmitted from the external apparatus, demodulate the received image data, output the demodulated image data, detect a wireless reception sensitivity of the image data, and output a reception sensitivity information corresponding to a result of detection; and
an image forming unit to change a time-out value based on the reception sensitivity information, and stop the reception of a data from the external apparatus as a time-out when a period of non-reception of the data exceeds the time-out value during the transmission of the image data from the external apparatus.

Abstract
An image forming apparatus that wirelessly transmits and receives data with an external apparatus, and has a wireless communication unit to receive image data transmitted from the external apparatus, demodulate the received image data, output the demodulated data, detect a wireless reception sensitivity of the image data, and output a reception sensitivity information corresponding to the a detection result. The apparatus also has an image forming unit varies a time-out value based on the reception sensitivity information, and stops the reception of a data from the external apparatus when during the transmission of the data from the external apparatus a period of non-reception of the data exceeds the time-out value. According to the wireless image forming apparatus, the success rate of wireless printing is improved even when communication is severed for a while due to the increase of obstacles on a communication path.

15. A wireless printing method comprising:
-
receiving image data;
detecting a wireless reception sensitivity of the image data;
selectively varying a time out value in accordance with the detected wireless reception sensitivity of the image data;
determining whether reception and printing of the image data are complete;
if reception and printing of the image data are not complete, determining whether a period of interruption of reception of the image data exceeds the varied time out value if the period of interruption of reception of the image data exceeds the varied time out value, completing printing and ending;
if the period of interruption of reception of the image data does not exceed the varied time out value, continuing to receive image data, detecting wireless reception sensitivity of the image data, and determining whether reception and printing of the image data are complete until one of the reception and printing of the image data are complete, and the period of interruption of reception of the image data exceeds the varied time out value; and
if reception and printing of the image data are complete, ending. - View Dependent Claims (16, 17)
