[cups] doubts about cutter option

[Osvaldo Parra]

sorry, I dont understand for complet,  I understand CutMedia should be an
option to choose for cut paper, but i dont understand how to add "CutMedia"
in print options, you mean on cups manager page?, or directly on ppd file,
like: *CutMedia 0x1d, 0x56, 0x42, 0x00 (1 of those 4)?

cheers
