you should be able to connect to the printer's IP from a web browser and access the protocols configuration, and close off the ones you do not require.  This can also be done to a certain extent via the Jetdirect card config on the actual device.

if you have Webjet Admin for HP printer management installed, this can be done very easily for all HP printers that you have the may have this feature.  Latest version is 10.2
