Jim, now that magical addition of next-server in dhcpd.conf file makes
them boot fast and removal of module_0 = printer from lts.conf makes them
boot correctly, i have a new problem: the print queeues are not
accessible. this is the typical entry in /var/log/messages:
Aug  7 22:37:55 ws044 lp_server: Started with: -n 9100 -w -d /dev/lp0
Aug  7 22:37:56 ws044 last message repeated 4 times
Aug  7 22:37:56 ws044 init: Id "p0" respawning too fast: disabled for 5
minutes

telnet ws044 9100 fails. many printers. what to do?
