Resolving spool files

All 

I have a situation using Infoprint to overlay pages of a document with
different layouts depending on a trigger field at the top of each printed
page. 

I can create a spool file on my development machine and all page breaks are
created correctly with the desired output from Infoprint.

When the programs are run on the live machine the spool file produced looks
similar but some page breaks are missing which ruins the formatting produced
by Infoprint.

When the spool file created on the live machine is transferred to the dev
machine the page breaks miraculously appear correctly!

We are on V4R5 on both machines. 

Any help would be very much welcomed 
TIA
