[cups.general] CUPS source port to printer:515

I've noticed that various printers at our university do not accept requests
from source ports below 1024. Also if I do a nmap scan with a high port the
port 515 on the printer is not shown. With source port 931 I get the status
of the port as open.

Also, I can print with the old lpr which actually is using a port around 900
as well as source port.

I tried to find a switch in cups to change the source port but no luck so
far. Can I force cups to do that?

thanks

Adrian
