I think hybrid is the best term. SLS seems to behave as though a 
program was being lauched every few seconds, checking to see if
there are spooled files waiting print and if not, exiting.  If you
select "About the Finder" and watch the memory allocation graph
you will see a block of memory allocated and de-allocated on a semi-
regular basis.

The problem is, the Mac locks up for a fraction of a second while this
lauch/check/exit process goes on.  This annoyed me so much I've gone
back to direct ImageWriter printing instead of their spooler.

In all fairness, I think PrintMonitor works in a similar fashion, but
I don't notice the delay when it works.
