Abstract

To reduce the amount of data transferred from an electronic apparatus to other electronic apparatus, a first compression unit compresses image data in units of m bits with a predetermined pattern to produce first compression data. A second compression unit compresses the first compression data in units of k bits to produce second compression data. And, an output unit outputs the second compression data according to a production order of the second compression data produced from the second compression unit.

Description

technical field [0001] The present invention relates to an information processing device that can perform data compression and output the compressed data to an external device, and also relates to its driver software, data transmission system, and electronic equipment. Background technique [0002] In general, an inkjet printer has a low-noise and compact body, and requires relatively low manufacturing and running costs. Therefore, many inkjet printers are widely used as general recording devices or duplicating machines. Among conventional inkjet recording apparatuses, a serial type inkjet recording apparatus can perform recording on a recording medium with its recording head. [0003] In particular, in order to reduce the capacity of the memory in the recording device, the area for one scan recording operation may be divided into a plurality of areas in the scanning direction. The master device can send data and commands for each independent area to the recording device. ...
