I understand the reason for CUPS' existence to be, not *discovering printers*, but *facilitating the ability to print*. That could involve discovering printers and presenting them as available, or it could involve only presenting as available a list of printers that have been entered into CUPS or otherwise set up in CUPS by some more manual means. (Among perhaps other possibilities.) Certainly at my workplace I understand that our Macs use CUPS for (network) printing, but at least at one point in our history (within the past decade), we had to go in and define each printer by IP address in CUPS on each Mac (or on the central machine which would be replicated to the others). I can certainly see it as being reasonable to want to be able to have CUPS perform printer discovery *on request*, and manually choose which of the discovered printers to add to the list of ones that will be remembered and shown as available when printing, but not have CUPS run discovery *automatically* and *automatically* add every discovered printer to that list. (I don't know with any confidence whether CUPS does the latter; I don't run it in enough environments with enough different available printers to have been able to make an assessment. However, I do have the impression that it may.) -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
