From volume2, page154:

"Note: If you designate a background procedure, you must set pIdleProc
AFTER presenting the dialogs, validating the print record, and initializing
the printing grafPort:  The routines that performs these operations
reset pIdleProc to NIL."

I got stung with this once myself, perhaps it is the problem in this case
as well.  Pretty simple fix if it is.
