Abstract

Provided is an information processing apparatus which transmits a file of to-be-printed data to a printer to perform printing, including: a determining unit which determines whether or not a data size of the file exceeds the predetermined receivable size of the printer; a reduction condition determining unit which predicts and determines a reduction condition; a reduction processing unit which reduces the data size of the file based on the determined reduction condition; and a re-determining unit which performs determination of the reduction condition of the reduction condition determining unit and the processing of reducing the data size of the file by the reduction processing unit again.

Claims

1. An information processing apparatus which transmits a file of to-be-printed data to a printer to perform printing, comprising:

a determining unit which determines whether or not a data size of the file exceeds a predetermined receivable size of the printer;

a reduction condition determining unit which predicts and determines a reduction condition where the data size of the file is equal to or smaller than the predetermined size from a data size reduction operation based on the number of pixels of the file which are extracted within a range where printing is not influenced in the case where the data size of the file exceeds the predetermined size and which determines the reduction condition by further changing a quantization table in the case where the data size of the file is not equal to or smaller than the predetermined size;

a reduction processing unit which reduces the data size of the file based on the determined reduction condition; and

a re-determining unit which performs determination of the reduction condition of the reduction condition determining unit and the processing of reducing the data size of the file by the reduction processing unit again in an ameliorated condition of the reduction operation so that the data size of the file is included within a suitable size range of which an upper limit is set to the predetermined size in the case where the data size of the file reduced by the reduction processing unit is smaller than the suitable size range.

2. The information processing apparatus according to claim 1, wherein the prediction of the reduction condition of the reduction condition determining unit further comprises a sampling condition changing process which changes a color component sampling condition into a predetermined sampling condition in a step before or after the data size reduction operation through the pixel extraction.

3. The information processing apparatus according to claim 1, wherein the file is a JPEG file.
