Claims

1. A printing system comprising an information processing apparatus and a printing apparatus, wherein the information processing apparatus includes:an extraction section that extracts a cross reference table and a trailer from a PDF file to be printed; anda transmission section that first transmits the extracted cross reference table and the trailer to the printing apparatus, and then transmits a body of the PDF file, and whereinthe printing apparatus includes:a reception section that receives the cross reference table and the trailer from the information processing apparatus and then receives the body; anda print processing section that starts print processing of the PDF file without waiting for completion of receipt of the body, by using the received cross reference table and the trailer.

2. An information processing apparatus comprising: an extraction section that extracts a cross reference table and a trailer from a PDF file to be printed; anda transmission section that first transmits the extracted cross reference table and the trailer to a printing apparatus, and then transmits a body of the PDF file.

3. The information processing apparatus according to claim 2, wherein, on the basis of a user instruction, selection is made as to whether or not there is performed processing of first transmitting the cross reference table and the trailer and then transmitting the body.

4. The information processing apparatus according to claim 2, wherein in a case where a capacity of the PDF file exceeds a specified capacity, there is performed processing of first transmitting the cross reference table and the trailer and then transmitting the body.

5. The information processing apparatus according to claim 2, wherein a capacity of the PDF file and a memory capacity of the printing apparatus are compared with each other, and, on the basis of a comparison result, selection is made as to whether or not there is performed processing of first transmitting the cross reference table and the trailer and then transmitting the body.

6. The information processing apparatus according to claim 2, wherein a judgment is made as to whether or not a processing of first transmitting the cross reference table and the trailer and then transmitting the body is effective in shortening of a print time, and in a case where the result of judgment shows that such processing is effective, the processing is performed.

7. A printing apparatus comprising: a reception section that receives, from an information processing apparatus, a cross reference table and a trailer of a PDF file to be printed and then receives a body of the PDF file; anda print processing section that starts print processing of the PDF file without waiting for completion of receipt of the body, by using the received cross reference table and the trailer.

8. A method of printing a PDF file, comprising: extracting a cross reference table and a trailer from a PDF file to be printed;transmitting the extracted cross reference table and the trailer first to a printing apparatus, and then transmitting a body of the PDF file;receiving the cross reference table and the trailer and then receiving the body; andstarting print processing of the PDF file without waiting for completion of receipt of the body, by using the received cross reference table and the trailer.

9. A method for transmitting a PDF file to a printing apparatus, comprising: extracting a cross reference table and a trailer from the PDF file to be printed; andtransmitting the extracted cross reference table and the trailer first to the printing apparatus, and then transmitting a body of the PDF file.

10. A method for printing a PDF file, comprising: receiving, from an information-processing apparatus, a cross reference table and a trailer of a PDF file to be printed and then receiving a body of the PDF file; andstarting print processing of the PDF file without waiting for completion of receipt of the body, by using the received cross reference table and the trailer.

11. A computer readable medium storing a program causing a computer to execute a process for transmitting a PDF file to a printing apparatus, the process comprising: extracting a cross reference table and a trailer from the PDF file to be printed; andtransmitting the extracted cross reference table and the trailer first to the printing apparatus, and then transmitting a body of the PDF file.

12. A computer readable medium storing a program causing a computer to execute a process for printing a PDF file, the process comprising: receiving, from an information-processing apparatus, a cross reference table and a trailer of a PDF file to be printed and then receiving a body of the PDF file; andstarting print processing of the PDF file without waiting for completion of receipt of the body, by using the received cross reference table and the trailer.

13. A computer data signal embodied in a carrier wave for enabling a computer to perform a process for transmitting a PDF file to a printing apparatus, the process comprising: extracting a cross reference table and a trailer from the PDF file to be printed; andtransmitting the extracted cross reference table and the trailer first to the printing apparatus, and then transmitting a body of the PDF file.

14. A computer data signal embodied in a carrier wave for enabling a computer to perform a process for printing a PDF file, the process comprising: receiving, from an information-processing apparatus, a cross reference table and a trailer of a PDF file to be printed and then receiving a body of the PDF file; andstarting print processing of the PDF file without waiting for completion of receipt of the body, by using the received cross reference table and the trailer.
