How do I reclaim an IP address from a DHCP client that keeps taking the address

I have a printer device that needs IP  somehow, while this printer was turned off, this address was accidentally taken by a DHCP laptop client in another building here on our network.  I want to "rip" away the address from this laptop client (forcing it to take a new, different address) and then give the .107 IP back to the printer device.  When I try to do this, however, in DHCP Server, the laptop keeps "winning".  I tried deleting the DHCP lease and DNS entries - created a reservation for so that it was no longer valid in the DHCP scope - and restarting the printer to renew its IP connection.  but nothing seems to work.  the laptop continues to retain the IP.  is there a way to do this, without needing to get access to the laptop?

Do not try to give the printer a static IP address within the DHCP range. This gives you the problem you have.

Go to the Printer Control Panel, network setup and give it an IP address that is not in the DHCP range above.

From there you can use a static IP address or a set up a DHCP Reservation range and use that for the printer (printer should have its address in this range)

John is spot on. Even if you do manage to take priority of that IP address another laptop or client down the road can create the same scenario. The only real way to prevent this is to assign some block of IP's for the printer/servers/Static IP dependent devices and narrow your DHCP scope so the clients stay out of that range. Managing your scope and static ranges is your best and only true solution of preventing IP conflicts like this from happening.

You can set a DHCP Reservation if you want. Or as above set IP that is not in DHCP Lease.

exclude printer IP from DHCP scope (create scope exclusion) and grant that IP as static IP to printer
Rob WilliamsCommented:
Though I always assign static IPs to printers, I also create a DHCP reservation for the same IP.  This does not create a conflict, and if some how the printer reverts to DHCP, such as a user resetting a device to defaults, it gets the same IP. As others suggested this is usually done outside the DHCP scope, but you can delete the existing assignment to the laptop and do this.  It will "tie up" the IP so it cannot be used by other devices.  Adding the static IP as a DHCP reservation also allows it to show up under DHCP leases for management proposes, you don't have to keep documentation of all static IPs.  A good practice is to assign IP ranges for devices, such as:
.01-.20 servers
.30 - .50 printers
.100 -.199 DHCP
.200 -.254 switches and routers

Fallow Mahesh advise, in this moment you have no choice, but you need to make sure that this address is not set permanently on laptop.
Double check in your DNS if this IP is set as Static or dynamic, before your action
If is static it mean client set this IP on IPv4 NIC properties, so if you'll create exclusion and set same address for printer you'll have more problems.

Some of this is as I posted in my first post.

@Damian_Gardner - Can you follow up please.

thanks for your help everyone.  I think I will move the printer IP outside of the scope - probably the best idea.  Thanks much to all

You are very welcome and good luck with your printer setup.
