      We know they need new Ethernet cabling in pretty much the whole office. lots of dead drops and other weird issues.

        I agree, it sounds like the Mac has a "sideband" conversation with the printer not going through the same channel as the Windows machines. So when the Windows machines have a hiccup through that channel the Mac has no idea that anything is wrong.

        Bonjour is a routeless protocol, like IPX or NetBEUI. Discovery works through IP but it broadcasts instead of point to point. So it can work on non-routeable IP addresses like 169.254. I would bet a buck that the Mac and printer are on the same switch.

        Other than cleaning up cabling and replacing crap switches, not much to do.

          I almost read that as a ruthless protocol.

            Yes, all on one brand new switch. Issue was there before the switch was replaced.

              Only one switch? Media drops between the printer and server only?

              Sounds less like bad cabling and such and more like someone broadcasting garbage onto the network. Perhaps too many devices running Bonjour or something like it clogging up broadcast.

                Only one switch in question. Multiple switches but its physically segregated (dedicated hardware voice network) not VLANs. So all of the printers and all of the desktops and laptops are on a single switch.

                  Only devices running Bonjour.

                    Got any cascaded switches behind it? Or, god forbid, a hub?

                    Yeah, smelling like a packet storm on the network is puking all the good stuff for higher level protocols. Parse the arp tables and see if you can find something out of place. I'll put the two bucks I won on the single switch stuff onto there being a crap "router" somewhere plugged in. Double or nuthin'!

                      There is a router. One router link goes to the voice switch, so that's completely separate. The other router link goes to the data switch (the one in question.) That switch has all direct attached desktops, servers, laptops, etc. It has one wireless AP attached to it and one additional switch hanging off of one port, but last I saw that switch was unused and only planned to be used for two devices in the foreseeable future. So probably not involved in any way.

                        Used to be six routers in there. They were all yanked out when the new switch was installed.

                          I'd still get an arp output from the switch. If you have that few amount of devices it's probably nothing to go through and read what MACs are there and compare it to the database of addresses. If you find something that doesn't belong, it's potentially your culprit.

                          Beyond that, usual troubleshooting. Trace, ping, das boot which has already been done. Etc. etc. etc.

                            If there were six routers before, and now there are two, and only one in question, did the default gateway for the printer change? That could explain why Bonjour works but standard Windows printing does not.

                              Two? Where did the second one come from?

                                You said that the VoIP devices were on their own network. Ok, I just realized I misread this statement:
                                "There is a router. One router link goes to the voice switch, so that's completely separate. The other router link goes to the data switch (the one in question.)"
                                My mind dropped the word link from the second sentence.

                                  Question remains the same though. If you had six routers before, and now only one, did the default gateway change during the migration?

                                    No, most of the extra routers were just creating loops.

                                      Ok, so is it a new router with the same IP or just the elimination of the extra mess?

                                        Same router. Just extra routers removed.
