I cannot print using my Brother machine on a wireless network (Mac)

I cannot print using my Brother machine on a wireless network (Windows)

Wireless setup is requesting a WPS PIN to complete the setup

I configured the "IP Config" method of the machine to "Auto" to assign an IP address automatically, however it was changed to "Static" unexpectedly. I get an error message that indicates IP address is not unique, or a document is printed out by the machine I didn't expected.

I am using Safari in Mac OS X. When I created a CSR or a Self-signed Certificate using the IP address to configure the "Common Name" and I try to access the Print Server using Safari with SSL communication, Safari issues an alert.

I want to use the Simple Network Configuration capabilities of Apple Mac OS X but I cannot find my printer in the "Print Center", "Printer Setup Utility" or "Default Printer Browser".
