How to enter User Authentication for a printer

Hi all,

Trying to print from my personal computer (MacBook Pro Yosemite 10.10.5) to a networked computer at work which requires an ID and password. In older versions of OS I could find "output method" under the printer settings, then click "User Authentication" to enter my password. But I cannot find that option anywhere, through any application or system preferences. Anyone have any insight?

For reference: the printer is a Konica Minolta bizhub 25e, and I already have the driver downloaded and installed.

Thanks all.
