crystal reports and Network printers using php

An application in php has to use 'crystal reports' for reporting purposes. and the reports should go to one of the networked printers selected. I need a solution (1)to get the php connected to 'crystal reports (crystal reports 2008)' (2)I should be able to see all the printers attached to the network, select a printer and the report should be printed to the selected network printer (selected thro' combo box). Programmer should have previous experience.
