4. The information processing apparatus as claimed in claim 1 , wherein the processor is configured to

further determine whether to generate the at least one second preview image from the second print data in response to completion of generating the at least one first preview image.

5. The information processing apparatus as claimed in claim 1 , wherein the processor is further configured to

receive a request to display a preview image of a specified page of the first print data from the image forming apparatus; and

generate the at least one second preview image from the second print data in response to a determination that the preview image of the specified page is not included in the generated at least one first preview image.

6. An information processing system comprising:

an information processing apparatus; and

an image forming apparatus,

wherein the information processing apparatus includes

a first memory; and

a first processor coupled to the first memory, and configured to

receive first print data from a client apparatus;

determine whether a print language used in the received first print data allows the first processor to generate a preview image for the first print data by specifying a page range of the first print data;

generate at least one first preview image of the first print data for a predetermined period from a start of generation of the at least one first preview image of an initial page of the first print data, in response to determining that the print language used in the received first print data does not allow the first processor to generate the preview image for the first print data by specifying the page range of the first print data; and

transmit the generated at least one first preview image to the image forming apparatus,

wherein the image forming apparatus includes

a second memory; and

a second processor coupled to the second memory, and configured to

display the at least one first preview image in response to an instruction from a user; and

transmit a signal to the information processing apparatus, the signal requesting transmission of a preview image of a page of the first print data specified by the user, and

wherein the first processor is configured to, in response to reception of the signal,

transmit the preview image of the specified page in response to a determination that the preview image of the specified page is included in the generated at least one first preview image; and

generate second print data for generating at least one second preview image that is not generated from the first print data during the predetermined period, in response to a determination that the preview image of the specified page is not included in the generated at least one first preview image, the second print data being the first print data from which a page of which the at least one first preview image is generated during the predetermined period is excluded.

7. The information processing system as claimed in claim 6 , wherein the first processor is further configured to store the at least one second preview image generated from the second print data as a preview image following the at least one first preview image generated from the first print data.

8. The information processing system as claimed in claim 6 , wherein the first processor is further configured to generate the at least one second preview image from the second print data in response to a determination that a number of pages of the generated at least one first preview image is less than or equal to a predetermined value.

9. The information processing system as claimed in claim 6 , wherein the first processor is configured to

further determine whether to generate the at least one second preview image from the second print data in response to completion of generating the at least one first preview image.

10. The information processing system as claimed in claim 6 , wherein the first processor is further configured to

receive the signal from the image forming apparatus; and

generate the at least one second preview image from the second print data in response to the determination that the preview image of the specified page is not included in the generated at least one first preview image.

11. A control method executed between an information processing apparatus and an image forming apparatus, the control method comprising:

the information processing apparatus executing a process that includes

receiving first print data from a client apparatus;

determining whether a print language used in the received first print data allows the information processing apparatus to generate a preview image for the first print data by specifying a page range of the first print data;

generating at least one first preview image of the first print data for a predetermined period from a start of generation of the at least one first preview image of an initial page of the first print data, in response to determining that the print language used in the received first print data does not allow the information processing apparatus to generate the preview image for the first print data by specifying the page range of the first print data; and

transmitting the generated at least one first preview image to the image forming apparatus;

the image forming apparatus executing a process that includes

displaying the at least one first preview image in response to an instruction from a user; and

transmitting a signal to the information processing apparatus, the signal requesting transmission of a preview image of a page of the first print data specified by the user; and

the information processing apparatus executing, in response to reception of the signal, a process that includes

transmitting the preview image of the specified page in response to a determination that the preview image of the specified page is included in the generated at least one first preview image; and

generating second print data for generating at least one second preview image that is not generated from the first print data during the predetermined period, in response to a determination that the preview image of the specified page is not included in the generated at least one first preview image, the second print data being the first print data from which a page of which the at least one first preview image is generated during the predetermined period is excluded.

12. The control method as claimed in claim 11 , further comprising:

the information processing apparatus executing a process that includes

storing the at least one second preview image generated from the second print data as a preview image following the at least one first preview image generated from the first print data.

13. The control method as claimed in claim 11 , further comprising:

the information processing apparatus executing a process that includes

generating the at least one second preview image from the second print data in response to a determination that a number of pages of the generated at least one first preview image is less than or equal to a predetermined value.

14. The control method as claimed in claim 11 , wherein

the information processing apparatus further executes a process that includes

determining whether to generate the at least one second preview image from the second print data in response to completion of generating the at least one first preview image.

15. The control method as claimed in claim 11 , further comprising:

the information processing apparatus executes a process that includes

receiving the signal from the image forming apparatus; and

generating the at least one second preview image from the second print data in response to the determination that the preview image of the specified page is not included in the generated at least one first preview image.

16. The information processing apparatus as claimed in claim 1 , wherein the predetermined period is preset in a timer.
