SPL-C is the manufacturer-supplied driver (Samsung Unified Print Driver). Therefore you obtained the best quality with this driver.
You did not test SpliX. You do not need to download SpliX from OpenPrinting, the version supplied by Ubuntu already supports your printer, and it supports it explicitly, you can directly choose the CLP-610 in system-config-printer.
Please test SpliX, as I am planning to make it the recommended driver to work around your printer's firmware bug. Therefore I want to know in which position is SpliX' print quality compared to the other drivers.
