Hey, not sure if it helps, but I worked with my brother to build a quick Microsoft Access data base to track our print cost, it doesn't estimate print costs (I think a lot of rips will do that) but you get a very good idea very quickly as to what your spend actually is..
you do not need access to run this, it's a stand alone..
first, it tracks the user (from windows login)
then you click "create a log"
you can then input the ink usage (got from printer) the media consumption, if it's mounted or not (this adds a set amount), the paper type. you also have an override cost. you can specify if it billable, personal or internal.
this gets logged and you can then run a report of previous prints.
you can set up multiple printers, papers, ink volumes etc..
for what I need, it works really well.
I'll upload it if anyone wants it?
