Unwanted CUPS header

[Petcan]

I am trying to send text files to a line printer using the command

'>cat file.txt | unix2dos | lpr -P seris_lpr'

Each time a print job is scheduled I get what looks to be a CUPS print header (see below). Is there some option I can set to stop the header?

I have used the command
>lpadmin -p seris_lpr -o job-sheets-default=none,none
to turn off banner pages.

I can see in /etc/cups/printers.conf that the printer config is update i.e. JobSheets none none

This seems to stop my unwanted banner but only when I run my lpr command as root.
When I run my lpr command as system I still get the unwanted banner! What am I doing wrong?
