Updating network printer
App Socket is a protocol that was developed by Tektronix that is very similar to HP Jetdirect.
1997 saw the new numbering format for both internal and external Jetdirect servers.Not until 1994 would MIO interface cards be released that could support more than one protocol per card.The next development releases added connection interfaces.The BT1300 is a Bluetooth compliant network adapter for network-ready parallel or USB printers.(Discontinued) The Print Server Appliance 4250 is perhaps the most ambitious of the Jetdirect products - being a complete printing facility in a box.
HP recommended to call them or contact them through the Web site and they will proceed to do some simple troubleshooting steps to determine if the failure is due to the chipset or some other cause.
