This is assuming the same file printed faster after reboot.
It definitely did. It went from unusable (sometimes more than a minute waiting to print) to pretty much normal. The problem was getting progressively worse until I rebooted everything, then it seemed OK. Suggestive of a memory leak, perhaps.
I thank everybody for their kind words about my wife Jean. I appreciate it. I'm signing off now, don't know for how long, it depends on whether I can make my wife's netbook computer work well enough to be useful.
