control dll from php to print a file

[Anon]

hello

I'm having a printer which can be controled via a DLL (WIN NT). Is it possible to control a dll via php?
The goal is to print out labels which contains dates from a mysql database.
I wrote functions which search the database and exports variables which now should be given to the printer. I only know, that it is possible to control the printer dll via VisualBasic. Can I do this by php too ?

Thanx for help

PS: The dll contains functions like:
-start printer, stop printer,...
