Ustn v7 to v8XM --- changes to printed page size/margins?

We have a printer driver for the HP Laserjet 5000 PS that we have been using for ages for 11"x17" format printing of 22"x34" sheets (commonly called quarter size printing). It was setup based on the actual printed page's size, working in conert with our batchprint border to produce exact scaled prints using layout settings = "maximize" and offset = 0,0

The page size in the PLT driver is this:

size=(10.75,16.75)/num=4/off=(0.25,0.24)/name=11x17 

Now my plots are not coming out to scale, roughly 95% too small.has anything changed in Ustn in recent times (To XM) that would add more margin space to the printed area?

; Stroke_tolerance determines tolerance for arcs and circles. Value is

; The style records define how the design file line codes (styles)
; are to be plotted. Values are in plotter units (resolutions).
; Values determine pen down/up movements, where (10,28) for a dot
; pattern leaves the pen down for 10 units and up for 28 units. The
; /nohardware switch causes software stroking with these values.
; This example has the /nohardware option commented
; out, so the printer will draw the styles.

; The weight line determines the number of strokes to use with each weight.
