• Install SpliX 2.0.0 (Right Click Open > Open)
• It will fail, but that's OK, it will install some of the prerequisites
• System Preferences > Select your USB Printer > Select Other > Select this file ml1610.ppd

Works for Samsung ML-1740 in my case!

UPDATE:

• Actually there is an entire list of PPDs here!

• Download http://splix.ap2c.org/ and unzip to get PPDs

• Select the PPD for your printer, mine was Samsung ML-1740 ml1740pt.ppd

• Download http://guigo.us/mac/splix/ Download and install SpliX 2.0.0

  • It will fail, that's OK, it still installs the prerequisities
  • Go to System Preferences > Printers > Install Printer > Select USB Printer > Select Other Driver > Select the PPD file.
