Web Development

we are using rundll32 printui.dll,PrintUIEntry /ia /m "OKI C5450n(PCL)" /h "Intel" /v "%_TREIBERUMGEBUNG%" /f c:\drivers\printer\OKI\OKI_C5450(PCL)\Ok72s2lu.inf for distributing drivers to our citrix farm. I would like to change the default options for the printer settings. for example Print Quality from 'High' to 'Normal'. I've found the file op5450n.dat in the subset, but don't know which value to chenge and if this is the only file to patch. File has syntax like ini-file
[COLORMODE]
UDcolormode=0
[COLORMODECOLOR]
UDcoloradjust=0
UDcoloradjustOpt=0
[RESOLUTION]
UDPrintQuality=0
Any good ideas welcome
