NT4 unitool.exe sMaxPhysWidth limitation

Hello,

I was trying to modify a minidriver sample HP laserjet III in NT4 ddk
by adding a 2400 dpi resolution. I see that the
PrinterData–>ModelData–>sMaxPhysWidth in unitool.exe can’t take more
than
32767 master units. So at 2400 dpi through the unitool.exe, I can’t
give
support for a paper size more than 32767/2400 = 13.6" at 2400 dpi. Can
someone tell me if this a limitation with the NT4 GPC based mindrivers
or
with NT4 ddk unitool.exe? If so, Is there a work around?

thanks
