So, I go th print to the HP LJ1200 attached to the Netgear PS110 print
server. This worked yesterday. Today, it says the printer is offline, and
clicking Use Printer Online brings back an Operation could not be completed
error. Delete the printer from Printers and Faxes, reinstall, printer is
back and working. I'm not looking for any help on this, since the fix is
obvious, but I'd be interested in hearing from anyone else having similar
travails.
