HP Colour Laserjet 4650 - Jetdirect Card - Latest Firmware installed - NDPS
manager shows SNMP Communication Failed - Problem: printer stops printing
intermittently - perhaps once every 2 days. - Replaced jetdirect card with a
new one. Changed the printer to a different ports on the switch - problem
still persists. Problem is cleared when the printer is turned off / on .
Many printers of a similar type in use - this is the only one with this
problem. Thanks in advance for any suggestions.
