[cups] doubts about cutter option

[Osvaldo Parra]

hi guys,

i added this lines to ppd file:

*OpenUI *CutMedia/Cut Media: Boolean
*OrderDependency: 10 AnySetup *CutMedia
*DefaultCutMedia: True
*CutMedia False/False: "<</CutMedia 0>>setpagedevice"
*CutMedia True/True: "<</CutMedia 4>>setpagedevice"
*CloseUI: *CutMedia

now cutter works and triggers after a job

thx you for all
