Hi Michael, is this correct?

*Choice "Res400/Res 400" "<</HWResolution[400 600]/cupsBitsPerColor 8/cupsColorSpace 0/cupsCompression 2>>setpagedevice"
Choice "Res600/Res 600" "<</HWResolution[600 600]/cupsBitsPerColor 8/cupsColorSpace 0/cupsCompression 3>>setpagedevice"
Choice "Res1200/Res 1200" "<</HWResolution[1200 1200]/cupsBitsPerColor 8/cupsColorSpace 0/cupsCompression 3>>setpagedevice"

Thanks
