Missing driver for printer - adobe postscript

I have a Panasonic Workio 190 Printer . It doesn't seem like there is a Mac driver (I'm on Mavericks). The only thing there is, is a Adobe PostScript Driver : I've never come across this kind of driver before and I don't want to go and install the wrong thing. Is it saying that this driver would allow the printer to work with my Mac, and are there any disadvantages to using the Adobe PostScript Driver? It seems like the only option I have at the moment. Any input would be much appreciated as to whether this is the software I need.
