port 515/tcp line printer spooler port. run print spooler listen port 515, but....

the modern, ubuntu way use cups (common unix printing system), listens internet printing protocol on port 631/tcp. read man cups. administer cups browser pointer http://localhost:631

and, easier way see what's listening (or not) port lsof (and more information):

$ sudo lsof -i tcp:515 -i tcp:631 [sudo] password w3:  command   pid user   fd   type  device size/off node name cupsd   17693 root   10u  ipv4 4833522      0t0  tcp *:ipp (listen) cupsd   17693 root   11u  ipv6 4833523      0t0  tcp *:ipp (listen)
