摘要:
A data recovery device is employed in a printer using a continuous form recording medium for reprinting data after printing has been interrupted. In the data recovery device, the number of pages remaining in a predetermined area of the feed path of the recording medium is counted. A plurality of page buffers are sequentially read out and printed. The printing operation is controlled such that the one of the data storing means from which the data is read out and printed by the printing means is identified based on the number of the pages remaining in the predetermined area.
