Sorry for the late reply. Insertfile works correctly except there are page counters on each document (page 1 of 2) that are in the headers that dissappear when I use insertfile.

I have tested with the delay and unless I put in an obnoxiously high pause like ten seconds, we end up with documents printed that ONLY contain signatures on them. No matter how much horsepower we throw at it (a gig of ram on the machine running it and the printer cards quadrupled), word is just brutally inefficient for high volume printing. At ten seconds a piece for 3,000 a day, that is too much spool time.

We are going with splitting up the job to multiple printers at the same time. The macro to print only works when running it from within a word document - if I run it from the Access database, it has all these effieciency problems.

The other option is to create PDF's and then combine them.

If I continue to test with the Insertfile option and try to fix the headers, I will report back with results.

As always, thanks for everyone's contributions.
