Is it a bare MDF? Give it a good clean before printing and if nothing works then try SEM plastic adhesion promoter. Works fine on papers as well:

I have printed on MDF and it worked fine...does it have any kind of coating/finish?

sorry for not replaying i was in vacasion
well i've tried to print on it without a primer ,didn't work.
with a primer the same thing ( may be the primer that i have is not good)
i just want to mentend that the mdf that i'm using is cover with a kind of white painting
i've tried to apply a car varnish on it after printing but it dammage the picture and i can easly remove the print.
ps: coating / finish: what do you mean by that
thank you.

That's pressure-laminated MDF. Nothing will stick to it.
