It's highly likely that I'm misunderstanding the problem/question here,
(especially since I've been using IDL object graphics for a whole hour
now) but, wouldn't the following code work?

xsize=29.7
ysize=21.0
;landscape

;set up a half scale window
oWindow = OBJ_NEW('IDLgrWindow', dimensions=[xsize/2.0, ysize/2.0],units=2)

oView = OBJ_NEW('IDLgrView',color=[200,200,200],$
LOCATION=[xsize/8.0,ysize/8.0], $
DIMENSIONS=[xsize/4.0,ysize/4.0],$
UNITS=2)

OScene = OBJ_NEW('IDLgrScene')
oScene->Add, oView

oModel = OBJ_NEW('IDLgrModel')
oView->Add, oModel
oText = OBJ_NEW('IDLgrText','Hello World',ALIGNMENT=0.5)
;yes, I know....

oModel->Add, oText
OWindow->Draw, oScene

c=obj_new('IDLgrClipboard',dimensions=[xsize,ysize], units=2)

oview->getproperty,dimensions=old_dimensions, $
location=old_location, $
units=old_units

oView->setproperty, dimensions=[xsize/2.,ysize/2.], $
location=[xsize/4.,ysize/4.], $
units=2

c->draw,/post,/vector,file='test.ps',oScene

oview->setproperty,dimensions=old_dimensions, $
location=old_location, $
units=old_units
wait,1
OBJ_DESTROY, oWindow
OBJ_DESTROY, oScene
obj_destroy,c

;(I think IDL always produces EPS files, when you ask for
postscript, it embeds the graphics in an A4 bounded box.)
