collate and staple

I have several Windows 7 64-bit PCs that are experiencing issues when printing to Canon iR-ADV devices.  When the user sets the output to multiple copies of a collated, stapled job, the output is collated, but all stapled together.  Instead of say 3 separate 4 page jobs each stapled (3 staples), we get 3 jobs and 1 staple.  When performing the same type of job from Microsoft Word on these PCs, the output is correct.  It appears that Adobe is trying to "help" the print driver....

Is there a way to disable Adobe's "interference" with the print jobs or a patch to fix this issue?

Thanks!
