Raster data for Pure black text printing

[shermin]

Hi,

  As i understood ,psto raster generates cups raster data.Before that pstops generates postscript data with page related information and all.So when i give a page to print,who is converting that data into postscript format.If this is done by ghostscript,then pstoraster is again a ghostscript code right.??

Please correct if my understanding above is wrong.
