this is a network problem of some kind rather than a problem with the printer.
Ummm... possibly not, because the printer acknowledged that it was receiving the data (ready light flashing) from the networked computer in five seconds (possibly less) from the time I told it to print. It just spent a long time chewing on it before it started to print.
I rebooted the computer
and the printer, and the problem seems greatly alleviated. At its worst it was taking several
minutes to print a 2MB file. Now it starts up pretty reliably in 8--10 seconds. Maybe that is as good as it ever was, and I only noticed it now because I was frantically reprinting page after page of scanned-in data to get insurance claims filled out before I leave here in about 11 hours.
