Thanks,<br />
I figured it out. I held down the Menu button while powering up, selected Initulize disk. After that it went into Ready mode and NIC worked out fine. It was a new NIC.

I need to replace the NIC on a HP LaserJet 550DN, I know what do do at my server/network end but not to sure what to do on the printer. I pull out the old one, power up printer while holding down the Go button to reset print. I then shutdown printer and install new NIC (with RJ45 not connected). Whne I power up all I get is a HP INVENT logo. Any suggestions?

A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
