Sorry, but I do not know what a UIN number is.

But your system is attempting to print to itself as a remote printer. The printcap definitions that you have have were not created by CUPS or anything else that I have seen before. So I suspect that whatever program that did that configuration will need to be uninstalled or at least terminated. You do not appear to be running a standard lpr installation. So I am not able to provide any assistance.

Perhaps somebody else here on LQ will be able to identify the configuration that you have and be able to provide additional assistance.

Sorry, I could not be of more help.
