Abstract
A method and system for preliminary data processing before printing is disclosed. The steps executed by said system comprises: dividing a page into a plurality of bands including a Mth band and a (M+1)th band; converting a color format of the Mth band; transferring the Mth band to a printer for storing, and converting the color format of the (M+1)th band in the period of transferring the Mth band; and printing the Mth band, wherein the printing does not start until the printer receives 50%-100% bands. During the printing, the color format of the residual bands continues to convert and the converted residual bands continue to transfer to the printer until the page is finished printing.

A method for preliminary data processing before printing, comprising:
- dividing a page into a plurality of bands including a Mth band, a (M+1)th band and a (M+2)th band;
- converting a color format of the Mth band from RGB format to CMYK format, translating the Mth band into a bit-map data after converting the color format of the Mth band, and compressing the Mth band having the CMYK format;
- transferring the converted, translated, and compressed Mth band from a host computer to a printer for storing, and converting the color format of the (M+1)th band from RGB format to CMYK format, translating the (M+1)th band into a bit-map data after converting the color format of the (M+1)th band, and compressing the (M+1)th band having the CMYK format in the period of transferring the Mth band;
- printing the Mth band, wherein the printing starts before the printer receives 100% of the plurality of bands;
- transferring the converted, translated, and compressed (M+1)th band from the host computer to the printer for storing, and converting the color format of the (M+2)th band from RGB format to CMYK format, translating the (M+2)th band into a bit-map data after converting the color format of the (M+2)th band, and compressing the (M+2)th band having the CMYK format in the period of printing the Mth band;
- and
- continuing to convert the color format, translate into bit-map data, and compress of the residual bands, and transferring the converted, translated, and compressed residual bands from the host computer to the printer until the page is finished printing.
A system for preliminary data processing before printing, comprising:
- a data distributing module, within a host computer, receiving a page of data, and dividing the page of data into a plurality of bands including a Mth band, a (M+1)th band and a (M+2)th band to write into a first memory unit, wherein the page of data has a RGB color format;
- a data processing module, within the host computer, reading the bands stored in the first memory unit, and converting the RGB color format into a CMYK color format, wherein the CMYK color format is a recognition format of a printer, wherein said data processing module translates the bands into a bit-map data after converting the color format of the bands, wherein said data processing module compresses the bands having the CMYK color format;
- and
- a second memory unit, within the host computer, to store the compressed bands having the second color format, wherein the data distributing module reads the converted, translated, and compressed Mth band in order to transfer the Mth band to a printer and the color format of the (M+1)th band is converted from RBG format to CMYK format, the (M+1)th band is translated into a bit-map data, and the (M+1)th band having the CMYK format is compressed in the period of transferring the Mth band, wherein the data processing module continues converting the color format, translating into bit-map data, and compressing of residual bands of the page, and transferring the converted, translated, and compressed residual bands from the host computer to the printer until the page is finished printing.
