Specification for CUPS printing options

I would like to ask if someone knows where can I find all the possible printing options the can CUPS send to backend/filter etc.

These are some of the possible options:

com.apple.print.PrintSettings.PMBorder..b.
com.apple.print.PrintSettings.PMBorderType..n.=1
com.apple.print.PrintSettings.PMColorMatchingMode..n.=0
com.apple.print.PrintSettings.PMColorSpaceModel..n.=0
com.apple.print.PrintSettings.PMCopies..n.=1
com.apple.print.PrintSettings.PMCopyCollate..b.

I would like to get the full list of these options, but can't find any specification for that.
