What is the print server username and password?

I am trying to install a Kodak ESP 5210 printer.

I set up the printer - it is on my wireless network.

I installed the Kodak printer software - it too installed correctly.

At the final step I need to "add printer" I click + in the printer window.
I then choose the kodakaio directory under "Windows".
I then choose kodakesp5200_00.
I am asked for the print server username and password.

I tried my log in password with just my first name in lowercase as username as this field was filled out by default.

I tried lots of different things, including no password, but the printer "Add" button never becomes not greyed out.

Would appreciate help. Kodak were no help.

I have pinged the printer successfully so its definitely on the network.

Thanks
