Pcounter and NDPS Printers

I had Pcounter 5.12f working well with Newtare 5.0 (SP6 with latest patches) queue based printing.

I’ve just migrated to NDPS printing and when a user prints, the jobs are shown as ready, but do not print. The only way to get it to print is to send another job or to press RESUME on the same job.

Any ideas
