CUPS Interface Script

[lee at citylightsphx.com]

Let me clarify the problem I am having.  When I send a print job to  the twoprint printer, the interface script I have defined for that printer is not getting executed.  I am trying to figure out why it is not being run when I send jobs to that printer.
