Printing PDF files to network printers

[Elly K]

Hi list, I have a bunch of PDF files being written to a common folder by different applications.  The users needs each of these files to be printed to specific printers on the network.

I am sure CUPS can print each of these files to specific printers on the network.  But how would CUPS know which PDF file needs to go to which printer?  Is there a way to do that?  Any ideas, pointers would be greatly appreciated... Thanks!
