Your company needs a central department to manage distributing IP addresses,
or at least a central database for people to go to reserve IP addresses and
check for their availability. This is just standard practice and common
sense, and this sort of problem will probably happen again unless something
like this is put into place.

I'm not sure about IBM printers, but most every device I can think of
working with does not request DHCP IP addresses if it has a static IP
address already assigned. The device needs to request a DHCP address before
it can get one. I would think that this can only be corrected by a setting
on the IBM printer, possibly by getting help from someone knowledgeable in
this type of printer. I'm thinking that possibly there is more than one
place to set more than one IP address, like perhaps a second IP address for
management?

This seems a little silly, but you could put a spare or inexpensive router
or firewall in front of the printer and block parts or all of the DHCP
communication [such as the initial broadcast, or perhaps UDP 67 and 68] from
the printer. [A $70 Netgear or Linksys BEFSR41 might be able to do this.]
