searching the utility
 

I`m looking for programm (or library)
that will compute number of pages
in .ps or .pdf and will estimate
percentage filling of document.
What can i use?
This is needed for print server
where users has quotas to print documents.

there's pdfinfo which will give you pdf page numbers, and you can always use ps2pdf to convert ps to pdf of course. but i'd be fairly sure there's going to be info in lpq or lpstat or your equivalent printing tools., which would seem like a nicer plan of action
