DHCP can assign IP addresses dynamically, but servers, including print serves, should have static IP addresses to avoid surprises.
Dynamic IP addresses are those which can change everytime one tries to connect to the internet whereas, Static IP addresses are those which stay fixed and do not change.
Dynamic memory changes and static stays the same.

It is a decision made by the ISP whether or not to allow static IP addresses. Most ISPs, in your case the phone company, do have static IP addresses available for an extra charge. Static IP addresses often require a business internet account.
If the laptops were not using dynamic address configuration, but were configured as static addresses, then the IP address may not work in another network, especially after they leave the meeting. They would need to set back the IP address acquisition to dynamic, rather than static.
Try to assign static IP addresses to servers?
A static IP address means it never changes. A dynamic one means that it changes between several different IP addresses. All you need to do is set up several IP addresses and then the software to randomly select one each time you connect to the Internet.
With a static IP address you have to manually configure each workstation, by hand. Doing so can lead to duplication errors because you mistyped an address that is already in use. You might also get the other settings wrong, such as the default gateway, DNS servers, etc. With DHCP you can more easily manage your address space in a network, and there will be no duplication because DHCP will not give out the same address twice. Other settings can be set once and then distributed to workstations automatically, without error. Finally, you can save on IP addresses because the workstations will use the addresses only as long as they need them, and then return them to the pool for other to use. With static addressing that will never happen, and you might run out of addresses for your network.
No, ISPs are free to assign either Static IPs or Dynamic IPs. Most prefer to assign Dynamic IPs as it gives them more freedom and allows them to support more users than their available IPs, as most users are only online for limited periods and don't need an IP when offline. Usually to get a Static IP a customer must request it from the ISP and pay an extra fee.
