The bundled AppleShare Print Server does this - The AppleShare IP File Server now lets an Appleshare File Server advertise its volumes at a TCP/IP address so they are reachable from an AppleTalk-enabled client looking for IP addresses. The Appleshare Print Server can attach a Queue to any printer it can see, which includes printers that only appear at IP addresses. >We have Macs and PC's on a ethernet, sharing HP 4MV on its own. >During some periods of the month, the Macs mysteriously refuse >to see the printer, or any other Macs for that matter. I was >told that the problem could be fixed by using TCP/IP rather than >Appletalk. The LaserJet 4MV has native support for AppleTalk, but its network interface card can be controlled by the - tetchy in early versions - HP JetAdmin (PC) program which controls the 4MV's JetAdmin NICard and how the 4MV appears over IPX/SPX, TCP/IP or both. You could conceivably be using JetAdmin to advertise an HP Ethernet printer like the 4MV for an AppleShare Print Server to attach to and control its queue without this printer appearing in the Chooser. Re. "disappearing printers", I find that AppleTalk over TCP/IP - theoretically faster and so using more of the available bandwidth - is less "tolerant" of any weakening of Ethernet signal strength such as when, for example, you extend one 10Base-T hub by adding another hub on a crossover port. As more nodes are attached to the hubs, it is ever more difficult to manage without "smart" switched hubs to boost your bandwidth and stop the whole network running out of steam. Typically, between 16 and 24 nodes you must upgrade from "simple" 10baseT hubs to more expensive solutions. If you think you are at a "transition" stage, temporarily disconnecting hubs should make the devices on the same hub appear to each other - and then you know you have to upgrade. When linking 4 "island Internets" of 12 -24 nodes each into a 100-node system, ALL the little hubs and hublets had to be replaced by a rack of 3Com switched hubs, though I was able to use an old PowerMac 7100 running Apple Internet Router 3.0.x to place the Macs in AppleTalk zones which helped the admin considerably. ( dedicated hardware routers that can do the same job too). With ASIP 5.0.2 on the Mac side and JetAdmin on the PC side the servers and printers should behave. I'm oversimplifying a lot here as every network has its quirks, but really sheer persistence always "solves" them in the end. Maybe this rather general ramble helps - if not I'd need more details to help some more.
