I would have, if I could remember. But I didn't keep good track; and, you might know, I did a whole series of things on one machine -- and then realized I had somehow gotten off #3 and onto #2 ... > On a fresh system, all you should have to do is connect a printer to the > print server computer, and let it sort itself out, or manually set that > printer up on the server.

Let me see if I have this straight. Having done most of the two footnoted parts above (maybe all -- I tried to), I *think* I can just go from client to client, deleting *all* printers (if all will let me; last time I tried that, as I said above, there was one that seemed immortal, afaict). If/when I get thepresent entries deleted, they will presumably once again find my wife's printer downstairs. They did last time, doubly : once as a printer and once as a fax. Does it hurt to have that there? Should I re-delete it, or maybe go shut her machine down (she's out of town) before I start telling clients to find printers? > * On my LAN, all the PCs are trusted explicitly, so I took the easy > option of setting the firewall to trust eth0 as a whole, rather than > particular ports.

I don't have such complications -- it's all on plain LAN, without subnets. But I don't follow how I share it only to the LAN -- unless that's what trusting eth0 and ippp+ do, perhaps?? > Perhaps you might want to allow remote administration of the server,and > allow users > to cancel any jobs, but that's icing on the cake, it's not needed just > to be able to print.

We don't normally fax things, nor receive faxes; but I can easily imagine it becoming convenient to be able to print to one another's printers, for instance if one breaks down or runs out of ink/ toner/whatever.

I haven't (yet, at least) done a thing about my wife's machine nor printer -- not made it either a client or a server. > Having said that, if you're reconfiguring a system which already had > printers configured all over the place on the clients, you'd want to > remove all those configurations, and then let them find the servers by > themselves, again. Hmmm ... Does that mean I need to go reconfigure my wife's CUPS in any case?? -- Beartooth Staffwright, PhD, Neo-Redneck Linux Convert Remember I know precious little of what I am talking about. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
