A follow-up question; we configure our printer(s) by giving the following command on the cups server:

  lpadmin -p Printer -o Collate=True

if I (or rather gtklp) does a:

  cupsGetOption("collate",act_printer->num_options,act_printer->options)

NULL is returned, while if I do a

  ppdFindMarkedChoice(printerPPD,"Collate")

'True' is returned. If I then do a save (i.e. creating a ~/.cups/lpoptions), subsequent calls to:

  cupsGetOption("collate",act_printer->num_options,act_printer->options)

returns 'true' and calls to:

  ppdFindMarkedChoice(printerPPD,"Collate")


returns 'True'.

Am I correct to assume that this means that 'ppdFindMarkedChoice' should be called to determine the preferred choice to use, and 'cupsAddOption' should be used for the actual printing?
