All ports are closed - Ubuntu 17

OK, so I have dabbled with Linux for a while but nothing too serious (so bear with me). Have set up Ubuntu as a main desktop and wanted to add a networked printer. Have set this up while ago using Lubuntu and all worked fine. However, this time I am struggling and have read a large number of threads but nothing helps. I cannot print and am getting various errors mainly saying that the printer is not found etc. I have used nmap and am getting "all 1000 scanned ports on (printer IP) are closed". This is rather odd, it's an out of the box install.
Have tried disabling iptables, same result. On the machine where I have lubuntu installed I get
Port State Service
91000/tcp open jetdirect
I can ping the IP address of the printer
Any idea what might be wrong? Is there something wrong with my network profile? firewall? Something different?

That doesn't sound right. What commands did you use? E.g. if my network was 192.168.1.x, I would donmap -sP 192.168.1.0/24to verify the devices. This also checks that you have a working network. If my printer was 192.168.1.10, I would then do:nmap -sS -F 192.168.1.10to look for the JetDirect port. How does that compare with what you did?

OK, sorry, just answered my own question. I did some more digging and the realised that my stupid sky router has given out the IP of my printer (fixed) to my machine. Totally odd, even though I have reserved the IP of that printer. Gave my machine a temporary fixed IP which is different from the printer and it's now working as on my other machine.
