Sorry JF - no billable hours :-). I fixed the "stream of events" problem

with PCL drivers. The problem was we were updating the changeid on every
SETPRINTERDATA/DELETEPRINTERDATA call. We should not do this, we should
just update the 'setprinter' called count. We update the changeid on calls
to SETPRINTER/ADDPRINTER/ADDPRINTEREX etc. Also fixed the correct returning
of the create time on printers.
