Just a quick thank you to all who offered advice and help. The errant Samsung hardware has started working again, so my search for a replacement is deferred -- at least for now.
In case it helps anybody else, the things that brought the machine back to life were rebooting the printer, clearing the network settings to factory default, reinstalling the Samsung driver (version 1-00-27.04) on my desktop PC, rebooting the printer... I might have thought it was the network settings, but I happen to have printed them out both before and after, and there is absolutely no difference. Whatever, it is great while it works. richard -- Richard Lyons -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
