I have 2 older HP printers and i keep getting "on port HP-COLOR-TN-HP ETHERNET MULTI-ENVIRONMENT,ROM C.25.80,JETDIRECT,JD115,EEPROM V.28.06 has a High Transmit Percent Utilization." When I look at that node I see the trasmit is thru the roof at times. I have gon e thru all the settings I can on the Jetdirect card. has anyone run into this issue with the older HP printers?
