According to this email, CUPS 1.1.x uses a linear lookup for printers, so it may just be too inefficient to handle 1000 print queues: http://marc.theaimsgroup.com/?l=samba&m=113165829420082&w=2 CUPS 1.2, which is supposed to fix this, is unfortunately still in beta. Another print server, such as LPRng, might be able to handle this better; I don't know.
