Ink jet recording apparatus
First Claim
Patent Images
1. An information processing apparatus comprising:
- means for transmitting an image forming signal to a printer controlling portion of an ink jet printer for performing a printing operation to form an image on a recording medium by discharging ink in response to the image forming signal;
a keyboard; and
a processing device for generating information used to create the image forming signal and for generating a predetermined signal different from the image forming signal and supplied to said printer controlling portion to effect a recovery operation for maintaining an ink discharging state of the ink jet printer, wherein the information processing apparatus counts an elapsed time from a time when a previous recovery operation was performed, at least one of a content and number of times the recovery operation is performed being varied by the predetermined signal based on the elapsed time.

Abstract
A recording apparatus includes a recording head having an ink ejection outlet for ejecting ink in response to recording data received from a main body of an information processing apparatus. A recover operation is performed on the recording head for restoring ink ejection and for preventing ink ejection failure, in response to a command from the main body of the information processing apparatus.
