One additional piece of data: on my USB1.1-connected Epson s-C82 under CUPS:
Every six or eight passes the printer pauses.  During this interval, the
computer's CPU usage spikes.  It looks as though there is some critical place
without needed double bufferring.  I don't know what this might do to a laser
printer, which needs to have room to stop and start, and may hold data back
if it sees that a stop is soon likely.  One of these days, when the world comes
to a stop and I can take a breath, I'm going to have a look at that and see if
I can fix it.
