Ghostscript is a filter app which converts various inputs to a PDL (page definition language) which a printer supports. I would recommend reading 'Printers' chapter in older edition of 'UNIX and Linux system administration handbook', it describes all things in human language :) Anyway, to learn more about printing, just write a filter which would `cat' input file to a 'output' file, you will see that top of the file data contains additional info like user invoking the printing etc... Very interesting for curious people. j.
