Abstract
An image recording system includes a host computer and a recording apparatus. The host computer generates image data to be recorded as an image. The recording apparatus includes a recording head, an image data generator, an error detector, and a selector. The error detector checks the condition of the recording apparatus to detect any errors. The selector switches between an on-line mode and an off-line mode of the recording system. In the on-line mode, the recording head is capable of recording the image on the recording medium in response to the image data supplied from the host computer. In the off-line mode, the recording means is capable of recording the predetermined image on the recording medium in response to the predetermined image data supplied from the predetermined image data generator. The selector switches to the on-line mode when the error detector does not detect an error and switches to the off-line mode when the error detector does detect an error.
