Printer incompatibility with MAC

I bought an Epson new generation printer which is not compatible with Air or Mac Pros and the sales people at Paarl Incredible Connection never told me. After spending tons of money on technical support the final outcome also confirmed by Incredible Connection themselves is that the printer does not work with Apple. Now the warranty is no longer applicable and anyway the printer is still working, just not on MAC and they say: "We can empathize but can not take responsibility"
