print related problem

hi there,

i got very complex problem.

see my base question is to listen "print" command on windows machine.

say for example when i do some printing of doc files in windows environment then that print command may be going to some print service or any of the dll should be listening it.

now what i want is i want to gether data i.e. in which format data will be printed on which page size, how much number of copy of page will be printed. ? etc.. etc..

so i think i need to develop one sevice which always ON and listens to the print command from any windows or any third paraty software.

so any idea ?

thanks for any help on the same in advance.

Thanks,
Nekin
