Do not print a document until the internal validation process returns ok in an external API

How do I keep a document submitted to the printer until I validate it in my API? My API returning OK, I had allowed the document to fall into the spooler.

You would have to pause the document then only un-pause it if the document is validated.
Ideally do this from an application running on the print server itself rather than on the client machines.
