Figure what netblock is used by DHCP, probably the same one already 
being used (, figure out what range of those addresses 
are not handed out by the DHCP server, and use one of those addresses 
for the print server.

For example, if the DHCP server is providing addresses from, give the print server a static address of, say,

Technically, you can probably continue to use the same address.  A 
decent DHCP server will ping an address before handing it out, to make 
sure that address is not already being used.  In practice, the firmware 
in routers can be terrible and should be replaced, if possible, with 
third-party firmware for sanity and safety.

Expert level for bonus points: set the DHCP server to hand out a fixed 
address to the print server based on MAC address.  The router might have 
a web interface to set this up.

Summary: continue to use a static IP address for the print server. 
Just make sure that address is inside the same netblock as the DHCP 
addresses, but preferably outside the range of dynamic addresses.
