Q: Printing to Samsung SCX-6545 with security not working

Hi guys!

I client of mine have a Samsung SCX-6545 printer on his mac and installed using Bonjour.

The latest drivers are installed by the way.

The printer has security enable in order to print.

It prompts user and password on windows but on Mac, it just prints this:

And of course, i didn't print that hahahahah.

Is there any way to tell Bonjour to print using a specific credential?

Thanks so much!

Regards.
