| 1. An information processing apparatus which is connected to an ink-jet printing apparatus that prints an image by ejecting
ink onto a print medium on the basis of print data, and can exchange data with the ink-jet printing apparatus, comprising:
print data generation means for generating print data for an image to be printed by the ink-jet printing apparatus;
transfer means for transferring the generated print data to the ink-jet printing apparatus; and
control means for controlling transfer of the print data by said transfer means in accordance with transfer permission/denial
information indicating transfer permission/denial of the print data, and operation information indicating an operation state
of the ink-jet printing apparatus, which are sent from the ink-jet printing apparatus,
wherein upon detection of transfer denial of the print data based on the transfer permission/denial information, said control
means controls said transfer means to wait without transferring the print data, and measures a time for waiting, and
wherein when said control means controls said transfer means to wait and receives next transfer permission/denial information
that permits transfer of the print data while the time for waiting is not more than a predetermined period of time, said control
means controls said transfer means to abort waiting, and to transfer the print data to the ink-jet printing apparatus.
