Print banner appearing with remote printing

Hi,
I have set up remote printing using a HP Direct Jet print server. Prints sent to the printer connected to the device prints fine except that at the end of the report the following info also appears - Users:, Class:, Job:. How can I disable this from printing.

Modify /usr/spool/lp/admins/lp/interfaces/model.orig/printerdestinationname
to not print the banner, or add -onobanner to the lp command.
