Cannot un-center plot on page

I have a command defined to plot from a button:

(defun c:15x21-HalfSizePlot()
(csplot)
(setvar "cmdecho" 0)
(command "-plot" "n" "" "15x21-HalfSizePlot" "" "n" "n" "y")
(setvar "cmdecho" 1)
)

All projects have the offset set to 0,0 (not center on page). But the
problem project decides it must be centered on the page and the plot is
shifted up. The Plot shifts up because my Oce TDS 600 does not have an
option to specify 15 in paper and I have to set it for 17 in paper. The
center on page therefore tries to center on a 17 in page. How can I stop
this?

I have tried using the detailed plot command as well and set the origin
offset, but the results are the same.
I have tried plotting manually and plot preview looks great but the file
gets centered again.
I have tried moving the paper in the plotter and then all the other projects
don't plot well.

jobcaptain!

any ideas?

Self healing.

It seems that all of the plots get centered on the plot paper in this
configuration. On the problem project there were some titleblock lines that
were missing and causing that project to center differently on the page.
The solution was to remake the pagesetup to account for and ignore any lines
outside of the titleblock area to be printed. Also had to shift the paper
over a little on the spool to realign the centered plot on differing paper
sizes, a 15" plot file and a 17" plot engine setting.
