Cannot connect to a network printer at work; can someone help?

Good Morning,

I recently purchased a MBP, and I really like it, but for some reason, I am having trouble with routine tasks. The problem that is vexing me right now is that I cannot connect to the network printer at work.

At work, we are all connected via WI-FI, and I have never had a problem logging into the network and using all of the applications that are made available to us. However, when I went to add the printer I have used for four years, I could not make it work. Here is what I have done so far:

I tried to find the printer in the Print and Scan window of System Preferences, but it never showed up. So, I tried to add it. I clicked on the IP icon in the menu bar, and I selected IPP. I entered the printer name, and received the message that it was an invalid address. To fix this, I walked down the hall to the printer, found its IP address, and entered it into the proper field in System Preferences. I then recevied the message that the address was valid. So, I tried to print a test page. No luck.

I then went to the Xerox website and downloaded all of the recent drivers for the WorkCentre 5665 and installed them. I selected the drivers from the Print Using drop-down menu. Still no luck.

So, I am now looking at the Print and Scan dialog box on my old computer, and I am looking at the printer's information that I am trying to set up on my new one. But, I am not sure what I should be looking for. Can anyone help me with this?

Thanks in advance.
