Help - Print Sharing via wireless network

Returned from the dark earlier side this year - yeah! Getting back into the Apple experience, but having some issues. Setup wireless network using belkin router and all is/works well except cannot print remotely from macbook.

Both imac and macbook using latest version of snow leopard; samsung clp-310 connected (USB) to imac and print sharing enabled for all users. Printer works fine from imac. Laptop recognizes samsung and sends print job to queue...then nothing happens and prompt in queue says "hold - authorization required"...what's up?

An ideas?

Thanks,

Mark
