complains that, as soon as a page starts printing on a LaserWriter
via PrintMonitor, his system responsiveness is almost completely gone
until the page has finished printing.

I have no such problem with PrintMonitor. The only effect I notice
on my machine (a vintage Mac II running System 6.0.7 and MultiFinder 6.1b9)
is that mouse tracking goes just a little bit funny while background
printing is in progress. This is a much milder version of the symptom you
get when doing floppy I/O, where interrupts get disabled for long periods
of time. This to me is a sign that PrintMonitor is doing most of its
work asynchronously at interrupt level, which is quite a reasonable design,
not subject to the vagaries of time-slicing under MultiFinder.

Anyway, the point is, PrintMonitor works fine for me.
