Printer problem, can anyone help?

[JEBB]

I was gifted a Oki B4300 laser printer but I can't get it to work. I want to use it attached to the USB port on my AEBS replacing a Cannon inkjet printer. Whether I have attached to my MacBook or to the AEBS it won't print and always gives me this message: Network host '127.0.0.1' is busy; will retry in 20 seconds...

Anyone recognize my problem and can suggest a fix? Thanks.
