Color managment oki c532

You can print, right? That gives hope.

Apple's Airprint (default OSX) driver (which is basically GimpPrint / GutenPrint) MIGHT work, its not a great driver as you lose some printer settings, but if all else fails it can be a life saver. As long as the OKI is supported [looking here I fear it MAY not be, if not, sorry]. 

If you go to System Preferences and with the printer on and connected choose install [if its on a network you'll need to enteer the IP addresse of the printer, USB connection is easier] it should appear in the list, then under "print using" select Airprint and let us know it it works at all.

Otherwise its get an old Mac and instal the printer driver on that then perhaps share it to your current one. I've loads of clients usomg older printer and RIP's [e.g. Colorburst Xproof] who run an older mac just to print.

I hope this helps
