Only one Answer to this, from Birger A. Wathne <>:
Yes, taking down Printers without stopping the Queues (using lpc) is
considered a bad_Thing (tm), and Crashes have been attributed to it.

Now, with one Printer moved to another Host and the second one staying
up 24h a Day, my Fileserver just reached 31.5 Days Uptime. Yippie!

One Day when I can't stand Life being so beautiful anymore, I'll test
the Configuration when the Printer's powered down with the Queue
stopped. Might be some Time til then. ;-)

No Answers to these.
