We have several different HP 4100 and 4200 series Printers on our network (Cisco).<br />
On all of them we use HP Jet Direct 615n EIO cards to connect to the network.<br />
The cards randomly just stop working, sometimes a card we just replaced a few days or weeks ago<br />
will stop, sometimes &nbsp;it's a card thats been in a printer since we go it.<br />
Any ideas about what might cause this?

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.

Printers and Scanners

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
