Hi,
The drivers from HP via the Samsung ML-2160 series support page (Samsung printers are now part of HP) appear to be for older Mac operating system versions only.
Would your printer possibly be compatible with the V3.93.08 universal driver at

Look upon this as an experiment. It may not work at all. You may have to select a different model (perhaps something like an M2020, or M2070?) if there is not an entry in the universal driver for your exact ML-2160 series printer.
As always, make sure that you have backup copies of all important files before testing anything. Software conflicts cannot be ruled out.
